The summary, key terms and the trap to avoid for every lesson, in order. Print it, or read it, cover it, and say it back.

Saying Latin out loud Beginning Latin · Sounds

  • c and g are always hard: k and g.
  • v is w; i before a vowel is y.
  • ae is ai, au is ou.
  • Two syllables: stress the first. Longer: stress the second-to-last if long (long vowel, or vowel before two consonants), else the one before.
  • Church Latin is a different, also valid, tradition.
classical pronunciation
how Latin was spoken in the 1st century BC
macron
the line over a long vowel: ā, ē, ī, ō, ū
diphthong
two vowels said in one syllable, like ae or au
penult
the second-to-last syllable of a word

Watch out: Saying v and c the English way: "VEE-nye, VYE-dye, VYE-sye" or "SISS-er-oh". In classical Latin, v is always w and c is always k.

Endings do the work Beginning Latin · How sentences work

  • Latin shows each noun's job with its ending, not its position.
  • First-declension subject: -a. Object: -am.
  • Word order can change for emphasis without changing who does what.
  • Read endings first, then put the English in order.
subject
who does the action; ending -a here
object
who receives the action; ending -am here
ending
the last letters of a word, which show its job
inflection
changing a word's ending to show its job

Watch out: Translating in the order the words appear: reading Nautam puella vocat as "the sailor calls the girl". Find the subject by its ending first, then the verb, then the object.

The five cases Beginning Latin · How sentences work

  • Five main cases: nominative, genitive, dative, accusative, ablative.
  • Each case is a job: subject, owner, to/for, object, by/with/from.
  • puella, puellae, puellae, puellam, puellā in the singular.
  • Genitive and dative share puellae: let the sentence decide.
case
the form a noun takes for its job in the sentence
nominative
subject case
genitive
owner case: of …, …'s
dative
indirect object: to / for …
accusative
direct object case
ablative
by, with, from, in …

Watch out: Mixing up genitive and dative, because both are puellae in the singular. Use the sentence to decide: rosa puellae (the girl's rose) is genitive; puellae dat (gives to the girl) is dative.

The first declension Beginning Latin · Nouns

  • First declension: nouns with nominative -a.
  • Singular: -a, -ae, -ae, -am, -ā. Plural: -ae, -ārum, -īs, -ās, -īs.
  • Find the stem by dropping -a, then add the endings.
  • Most are feminine; nauta, agricola and poēta are masculine.
declension
a group of nouns that share one set of endings
stem
the part that stays the same: puell-
singular / plural
one / more than one
feminine / masculine
the grammatical gender of a noun

Watch out: Assuming every -a noun is feminine. Most are, but a few words for men's jobs are masculine: nauta (sailor), agricola (farmer), poēta (poet). They still use the first-declension endings.

Adjectives agree with their nouns Beginning Latin · Nouns

  • An adjective agrees with its noun in gender, number and case.
  • Feminine: bona, pulchra. Masculine: bonus, pulcher.
  • Masculine -a nouns (nauta, agricola) take masculine adjectives.
  • Adjectives often follow their noun, but can come first for emphasis.
agree
match the noun in gender, number and case
bona
good (feminine)
bonus
good (masculine)
pulchra
beautiful (feminine)

Watch out: Making the adjective's ending look like the noun's: agricola bona. Agricola ends in -a but is masculine, so the adjective takes its masculine form: agricola bonus. Agreement is about gender, number and case, not about matching letters.

The second declension Beginning Latin · The second declension

  • Second declension: genitive singular -ī.
  • -us nouns are mostly masculine; -um nouns are neuter.
  • dominus: -us, -ī, -ō, -um, -ō; plural -ī, -ōrum, -īs, -ōs, -īs.
  • Neuter: nominative and accusative plural in -a (pīla).
  • Vocative of -us nouns ends in -e (domine).
second declension
nouns with genitive singular in -ī
neuter
neither masculine nor feminine; nouns in -um
vocative
the case for calling someone: Domine!
dominus, -ī, m.
master
pīlum, -ī, n.
spear

Watch out: Giving a neuter plural the ending -ī: wrong: pīlī for "spears" as a subject or object. Neuter nouns end in -a in the nominative and accusative plural: pīla, oppida, bella.

Predicate nouns and apposition Beginning Latin · The second declension

  • After est / sunt, a noun that says what the subject is takes the subject's case.
  • A noun in apposition copies the case of the noun it explains.
  • A predicate noun is nominative when the subject is; an appositive can be in any case.
predicate noun
a noun after est / sunt that says what the subject is
apposition
a noun placed beside another to explain it, in the same case
lēgātus, -ī, m.
lieutenant, envoy
agricola, -ae, m.
farmer

Watch out: Leaving the appositive in the nominative: wrong: Mārcum lēgātus laudant. The explaining noun copies the case of the noun it explains: Mārcum lēgātum.

Adjectives in all three genders Beginning Latin · The second declension

  • bonus, bona, bonum: masculine like dominus, feminine like puella, neuter like pīlum.
  • Choose the adjective by the noun's gender, number and case.
  • nauta bonus, agricola bonus: masculine nouns of the first declension take masculine adjectives.
bonus, -a, -um
good
magnus, -a, -um
big, great
parvus, -a, -um
small
malus, -a, -um
bad, wicked

Watch out: Copying the noun's ending instead of choosing by gender: wrong: agricolārum bonārum for "of the good farmers". Agricola is masculine: agricolārum bonōrum.

Nouns in -ius, -er and -ir Beginning Latin · The second declension

  • -ius / -ium nouns: genitive singular in -ī (fīlī, praesidī).
  • fīlius and names in -ius: vocative in -ī (fīlī, Vergilī).
  • puer keeps its e (puerī); ager drops it (agrī); vir is regular (virī).
  • Learn the genitive with every noun.
fīlius, fīlī, m.
son
puer, puerī, m.
boy
ager, agrī, m.
field
vir, virī, m.
man
līberī, -ōrum, m. pl.
children (literally "the free-born")

Watch out: Guessing whether the e stays. Puer keeps it (puerī), but ager drops it, so wrong: agerī is wrong: agrī. Always learn the genitive with the noun.

My, your, his, our Beginning Latin · Pronouns and adjectives

  • meus, tuus, suus, noster, vester are declined like adjectives.
  • They agree with the thing possessed in gender, number and case.
  • tuus for one owner, vester for more than one.
  • suus refers back to the subject: his / her / their own.
  • The vocative of meus is mī: mī fīlī.
meus, -a, -um
my
tuus, -a, -um
your (one owner)
suus, -a, -um
his / her / its / their own (the subject's)
noster, -tra, -trum
our
vester, -tra, -trum
your (more than one owner)

Watch out: Choosing tuus or vester by politeness, as in French tu and vous. In Latin it depends only on the number of owners: one owner tuus, more than one vester.

Four ways to say "with" Beginning Latin · The ablative

  • Cause and means: plain ablative, normally no cum.
  • Accompaniment: cum + ablative.
  • Manner: cum + ablative; cum may drop when there's an adjective.
  • Ask: because of what, with what, with whom, how?
ablative of cause
because of what; no cum
ablative of means
with what, by means of what; no cum
ablative of accompaniment
with whom; cum
ablative of manner
how; cum, which may be left out with an adjective

Watch out: Putting cum before a tool or a cause: wrong: cum pīlīs pugnant for "they fight with spears". The rule to learn now: cum for company and manner, the plain ablative for means and cause. (Later you will meet cum with weapons meaning "armed with".)

The nine irregular adjectives Beginning Latin · Pronouns and adjectives

  • UNUS NAUTA: ūnus, nūllus, ūllus, sōlus, neuter, alius, uter, tōtus, alter.
  • Genitive singular -īus, dative singular -ī, in all genders.
  • Otherwise like bonus; plural regular; alius has neuter aliud.
  • alter … alter = the one … the other; aliī … aliī = some … others.
ūnus, -a, -um
one
tōtus, -a, -um
whole, entire
alius, -a, -ud
another (of several)
alter, -era, -erum
the other (of two)
uter, utra, utrum
which? (of two)

Watch out: Using the regular endings in the genitive and dative singular: wrong: nūllae puellae for "of no girl". The nine use nūllīus puellae, and the dative nūllī puellae.

is, ea, id: this, that, he, she, it Beginning Latin · Pronouns and adjectives

  • is, ea, id = this / that, and he / she / it.
  • Genitive eius, dative eī, accusative eum, eam, id.
  • suus = the subject's own; eius / eōrum / eārum = someone else's.
is, ea, id
this, that; he, she, it
eius
his, her, its (not the subject's)
eōrum / eārum
their (not the subject's)
suus, -a, -um
his / her / their own (the subject's)

Watch out: Using eius for the subject's own things: wrong: Mārcus eius equum cūrat for "Marcus looks after his own horse". That eius would mean someone else's horse. Use suum: Mārcus suum equum cūrat.

sum: I am, I was, I shall be Intermediate Latin · Verbs: the present system

  • Endings show the person: -ō/-m, -s, -t, -mus, -tis, -nt.
  • Present: sum, es, est, sumus, estis, sunt.
  • Imperfect: eram, erās, erat, erāmus, erātis, erant.
  • Future: erō, eris, erit, erimus, eritis, erunt.
sum, esse
to be
personal ending
the ending that shows the person: -ō/-m, -s, -t, -mus, -tis, -nt
hodiē
today
mox
soon
nūper
recently

Watch out: Mixing up eris (you will be) and erās (you were). The future has -i- (eris, erit, erimus, eritis); the imperfect has -a- (erās, erat, erāmus, erātis).

The present of amō and moneō Intermediate Latin · Verbs: the present system

  • Infinitive -āre: 1st conjugation; -ēre: 2nd; -ere: 3rd; -īre: 4th.
  • Present = stem + personal ending: amō, amās, amat, amāmus, amātis, amant.
  • moneō keeps its e: moneō, monēs, monet …
  • One Latin present = "I love", "I am loving" or "I do love".
conjugation
a group of verbs that share one pattern
infinitive
the "to …" form: amāre, to love
stem
the infinitive without -re: amā-, monē-
habeō, habēre
have
videō, vidēre
see

Watch out: Missing the -e- in the second conjugation's "I" form: wrong: monō. The first conjugation contracts (amā-ō → amō), but the second keeps both vowels: moneō, videō, habeō.

The imperfect: was doing Intermediate Latin · Verbs: the present system

  • Imperfect = stem + -bā- + ending.
  • First person ends in -m: amābam.
  • Meaning: was …ing, used to …, kept …ing.
  • Same pattern for the 1st and 2nd conjugations.
tense sign
letters added to show the tense: -bā- for the imperfect
imperfect
was doing / used to do
saepe
often
arō, arāre
plough

Watch out: Translating the imperfect as a single finished action ("he ploughed once"). It shows something in progress or repeated: was ploughing, used to plough. The completed past comes later, with the perfect tense.

The future: will do Intermediate Latin · Verbs: the present system

  • Future = stem + -bi- + ending: amābō, amābis, amābit, amābimus, amābitis, amābunt.
  • Endings match erō, eris, erit.
  • -bā- = past (imperfect); -bi-/-bu- = future.
future
will do, shall do
-bi-
the future tense sign in the 1st and 2nd conjugations
crās
tomorrow
moneō, monēre
advise, warn

Watch out: Confusing -bant (imperfect: were) and -bunt (future: will). One vowel changes the time: vocābant they were calling, vocābunt they will call.

The dative with adjectives Intermediate Latin · Verbs: the present system

  • Adjectives of nearness, friendship, pleasing and fitness, and their opposites, take the dative.
  • The dative answers "to whom?" or "for what?".
  • A singular first-declension -ae that the quality is directed to is dative.
amīcus
friendly (to); as a noun, friend
inimīcus
hostile (to); as a noun, enemy
grātus
pleasing (to)
idōneus
suitable (for)
fīnitimus
neighbouring (to)

Watch out: Reading the dative as "of": rēgīnae grātus is "pleasing to the queen", not "the queen's pleasing". With these adjectives, a singular first-declension noun in -ae that the quality is directed to is the dative (though -ae can also be a nominative plural elsewhere).

The present of regō and audiō Intermediate Latin · Verbs: the present system

  • regō: regō, regis, regit, regimus, regitis, regunt.
  • audiō: audiō, audīs, audit, audīmus, audītis, audiunt.
  • 3rd: short e → i, and u before -nt. 4th: long ī, with -iunt.
  • -ēre (long) = 2nd; -ere (short) = 3rd.
regō, regere
rule
dūcō, dūcere
lead
mittō, mittere
send
audiō, audīre
hear
veniō, venīre
come

Watch out: Treating regere like monēre because both infinitives end in -ere. Check the vowel: monēre has a long ē (second conjugation: monēmus); regere has a short e (third: regimus). A dictionary shows it with a macron or by giving the full forms.

The imperfect of regō and audiō, and verbs that take the dative Intermediate Latin · Verbs: the present system

  • 3rd and 4th conjugation imperfect: regēbam, audiēbam (…ēbā…).
  • crēdō, faveō, noceō, pāreō, persuādeō, resistō and studeō take the dative.
  • Think "give belief / obedience / resistance to".
crēdō, crēdere (+ dat.)
believe, trust
noceō, nocēre (+ dat.)
harm
pāreō, pārēre (+ dat.)
obey
resistō, resistere (+ dat.)
resist
studeō, studēre (+ dat.)
be eager for, study

Watch out: Using the accusative after these verbs: wrong: rēgīnam pārent. Think "give obedience to the queen": rēgīnae pārent.

The future of regō and audiō Intermediate Latin · Verbs: the present system

  • 3rd and 4th conjugation future: -am, -ēs, -et, -ēmus, -ētis, -ent.
  • 4th keeps its i: audiam, audiēs …
  • Third-conjugation future looks like second-conjugation present: check the conjugation.
regam, regēs, reget
I shall / you will / he will rule
audiam, audiēs, audiet
I shall / you will / he will hear
nūntius, -ī, m.
messenger, message

Watch out: Reading regēs or mittet as present. In the second conjugation monēs is present, but in the third regēs is future. Check the infinitive: regere (short e) is third conjugation, so regēs = you will rule.

capiō, and giving orders Intermediate Latin · Verbs: the present system

  • -iō verbs (capiō, faciō, fugiō, iaciō, rapiō) are third conjugation.
  • They take an i where audiō has two vowels together: capiunt, capiēbam, capiam.
  • Imperative: stem for one person (amā), + -te for more (amāte).
  • Short forms: dīc, dūc, fac.
capiō, capere
take, seize
faciō, facere
make, do
fugiō, fugere
flee
imperative
the mood for orders: amā! amāte!

Watch out: Calling capiō fourth conjugation because of the -iō. Check the infinitive: capere (short e) is third, so the present is capis, capit, not wrong: capīs, capīt.

The passive: being done to Intermediate Latin · The passive voice

  • Passive = the subject receives the action.
  • Endings: -r, -ris, -tur, -mur, -minī, -ntur (present "I": -or).
  • Same tense signs: -bā- (imperfect), -bi- (future).
  • amor, amābar, amābor: I am / was being / shall be loved.
active voice
the subject does the action
passive voice
the subject receives the action
-tur, -ntur
passive "he / she / it", "they"
vāstō, vāstāre
lay waste
oppugnō, oppugnāre
attack

Watch out: Missing the passive because the stem looks familiar. Check the ending: vocant (they call) but vocantur (they are called); vocābit (he will call) but vocābitur (he will be called).

The passive of regō, audiō and capiō; passive infinitives Intermediate Latin · The passive voice

  • Passive endings go on the tenses you know: regor, regēbar, regar.
  • regō "you": present regeris, future regēris.
  • capiō: capior, capiuntur like audiō; caperis, capitur like regō.
  • Passive infinitive: amārī, monērī, regī, capī, audīrī.
regī
to be ruled
audīrī
to be heard
capī
to be taken
present passive infinitive
"to be …ed"

Watch out: Making the passive infinitive of the third conjugation like the others: wrong: regerī. The third conjugation drops -ere and adds -ī: regī, mittī, capī.

Synopses, and the ablative of "from" Intermediate Latin · The passive voice

  • Synopsis: one person, every tense, active and passive.
  • From a place: ā/ab, ē/ex, dē + ablative.
  • Separation: ablative, with a preposition if there is real movement.
  • By a person (with a passive): ā/ab + ablative. By a thing: plain ablative.
synopsis
one person of a verb in every tense
ā / ab
from (near); by (a person)
ē / ex
out of
dē
down from; about
prohibeō, prohibēre
keep (away) from
superō, superāre
overcome, defeat
personal agent
the person by whom a passive action is done

Watch out: Using the plain ablative for a person: wrong: Oppidum Gallīs oppugnātur. A person who does the action takes ā / ab: ā Gallīs. A thing used takes no preposition: pīlīs oppugnātur, it is attacked with spears.

fuī, fueram, fuerō: the perfect tenses of sum Intermediate Latin · The perfect tenses

  • Principal parts: present, infinitive, perfect, perfect passive participle.
  • Perfect stem = perfect minus -ī.
  • Perfect endings: -ī, -istī, -it, -imus, -istis, -ērunt.
  • Pluperfect = stem + eram; future perfect = stem + erō (they: -erint).
principal parts
the four forms you learn: sum, esse, fuī; amō, amāre, amāvī, amātus
perfect stem
the perfect without -ī: fu-
perfect
completed: have been, was
pluperfect
had been
future perfect
will have been

Watch out: Using -erunt for the future perfect "they": wrong: fuerunt. The future perfect is fuerint; fuērunt (long ē) is the perfect.

The perfect active: did, have done Intermediate Latin · The perfect tenses

  • Perfect = perfect stem (third principal part minus -ī) + -ī, -istī, -it, -imus, -istis, -ērunt.
  • 1st conjugation: usually -āvī.
  • Perfect = did / have done; imperfect = was doing.
  • In stories: perfect for events, imperfect for background.
perfect active
I did / I have done
third principal part
the perfect, first person: amāvī
dūcō, dūcere, dūxī
lead
mittō, mittere, mīsī
send
veniō, venīre, vēnī
come

Watch out: Building the perfect from the present stem: wrong: mittī for "I sent". The perfect stem often looks different, so always learn the third principal part: mīsī.

Had done, will have done: pluperfect and future perfect active Intermediate Latin · The perfect tenses

  • Pluperfect = perfect stem + eram, erās, erat …: had done.
  • Future perfect = perfect stem + erō, eris, erit … erint: will have done.
  • Perfect infinitive = perfect stem + isse.
  • -erā- had; -eri- will have.
pluperfect
had done: perfect stem + eram
future perfect
will have done: perfect stem + erō
perfect infinitive
to have done: perfect stem + isse
synopsis
one person of a verb in every tense
epistula, -ae
letter

Watch out: Mixing up -erat and -erit. Pluperfect has -erā- (had), future perfect has -eri- (will have): vīderat, he had seen; vīderit, he will have seen.

amātus sum: the perfect passive Intermediate Latin · The perfect tenses

  • Fourth principal part: perfect passive participle, -us, -a, -um.
  • Perfect passive = participle + sum; pluperfect + eram; future perfect + erō.
  • The participle agrees with the subject.
  • Infinitives: amātus esse (perfect passive), amātūrus esse (future active).
perfect passive participle
having been …ed: amātus, -a, -um
amātus sum
I was (have been) loved
amātus eram
I had been loved
amātus esse
to have been loved
amātūrus esse
to be about to love
cōnsilium, -ī
plan
epistula, -ae
letter

Watch out: Reading amātus est as present: wrong: he is loved. Est is present, but the phrase is perfect: he was (has been) loved. Likewise amātus erat is "had been loved", not "was loved".

Principal parts, prepositions, and yes-or-no questions Intermediate Latin · The perfect tenses

  • Four principal parts: present, infinitive, perfect, participle.
  • Ablative: ā/ab, cum, dē, ē/ex, prō, sine. Accusative: ad, apud, per.
  • in + ablative = in, on; in + accusative = into, against.
  • -ne (open question), nōnne (expects yes), num (expects no).
principal parts
present, infinitive, perfect, participle
-ne
question sign, no answer expected
nōnne
expects "yes"
num
expects "no"
in + accusative
into, against
epistula, -ae
letter

Watch out: Using num for a neutral question. Num expects the answer no. For a plain question, add -ne to the first word, usually the verb: Vēnitne? Has he come?

possum, "I can", and the infinitive Intermediate Latin · The perfect tenses

  • possum = pot- + sum; pos- before s: possum, potes, potest, possumus, potestis, possunt.
  • Perfect potuī; infinitive posse.
  • Infinitive completes a verb: possum vidēre.
  • Subject of an infinitive: accusative (iussit virōs fugere).
  • Infinitive as a noun: neuter singular (vidēre est crēdere).
possum, posse, potuī
be able, can
complementary infinitive
completes a verb: possum vidēre
subject accusative
the subject of an infinitive is accusative
iubeō, iubēre, iussī, iussus
order
grātus, -a, -um
pleasing

Watch out: Putting the subject of the infinitive in the nominative: wrong: Lēgātus cōpiae venīre iussit. After iubeō, the person told to act is accusative: cōpiās venīre iussit.

quī, quae, quod: who, which, that Intermediate Latin · Pronouns

  • quī, quae, quod: who, which, that.
  • Gender and number from the antecedent; case from its own clause.
  • quis, quid: who? what? (pronoun).
  • quī, quae, quod before a noun: which …? what …?
relative pronoun
who, which, that: quī, quae, quod
antecedent
the noun the relative refers to
quis, quid
who? what? (pronoun)
quī, quae, quod (question)
which …? what …? (adjective)
interficiō, interficere, interfēcī, interfectus
kill
fēmina, -ae
woman

Watch out: Copying the antecedent's case: wrong: virōs quōs captī sunt. Virōs is accusative in the main clause, but inside its own clause the relative is the subject, so it is nominative: quī captī sunt.

rēx, rēgis: the third declension Intermediate Latin · The third declension

  • Learn every third-declension noun with its genitive; drop -is for the base.
  • Masc./fem.: -s or none, -is, -ī, -em, -e; -ēs, -um, -ibus, -ēs, -ibus.
  • Neuter: nominative = accusative; plural -a.
  • The nominative often hides the base: rēx (rēg-), mīles (mīlit-), flūmen (flūmin-).
rēx, rēgis, m.
king
mīles, mīlitis, m.
soldier
pater, patris, m.
father
māter, mātris, f.
mother
legiō, legiōnis, f.
legion
flūmen, flūminis, n.
river
tempus, temporis, n.
time

Watch out: Using the nominative as the base: wrong: mīlem, wrong: flūmenis. The nominative is often changed (rēg-s → rēx, mīlit-s → mīles). Always build from the genitive: mīlitem, flūminis.

hostis, urbs, mare: i-stems Intermediate Latin · The third declension

  • i-stems: -ēs/-is nouns with equal syllables; -ns, -rs; one-syllable -s/-x after a consonant; neuters in -e, -al, -ar.
  • Masc./fem.: genitive plural -ium; accusative plural -īs or -ēs.
  • Neuters: ablative -ī; plural -ia, -ium.
hostis, hostis (-ium), m.
enemy (in war)
urbs, urbis (-ium), f.
city
cīvis, cīvis (-ium), m. and f.
citizen
nāvis, nāvis (-ium), f.
ship
mare, maris (-ium), n.
sea
animal, animālis (-ium), n.
animal
i-stem
a third-declension noun with -ium in the genitive plural

Watch out: Treating every -is noun as an i-stem. Hostis, hostis is (same syllables), but mīles, mīlitis and lapis, lapidis are not: their genitives are longer, so they have mīlitum and lapidum.

vīs and iter; gender in the third declension Intermediate Latin · The third declension

  • vīs: vīs, vim, vī; plural vīrēs, vīrium (strength).
  • iter, itineris, n.
  • Masc.: -or, -ōs, -er, -es (-itis). Fem.: -ō, -is, -x, -s. Neut.: -e, -al, -ar, -n, -ur, short -us.
  • Males are masculine; learn the listed exceptions.
vīs, vīs, f.
force; plural vīrēs, strength
iter, itineris, n.
journey, march, route
mōns, montis (-ium), m.
mountain
arbor, arboris, f.
tree
gender rule
the nominative ending gives a likely gender; learn the exceptions

Watch out: Treating -us in the third declension like -us in the second. Tempus, opus, corpus are neuter: magnum tempus, not wrong: magnus tempus. Check the genitive: -oris or -eris means third declension.

omnis, ācer, pār: third-declension adjectives Intermediate Latin · The third declension

  • Three endings (-er), two (-is, -e), one (pār).
  • Declined like i-stems; ablative singular always -ī.
  • Neuter plural -ia; genitive plural -ium.
  • They can go with nouns of any declension.
omnis, omne
every; plural all
fortis, forte
brave
facilis, facile
easy
difficilis, difficile
difficult
brevis, breve
short
ācer, ācris, ācre
keen, sharp
pār (gen. paris)
equal

Watch out: Expecting the adjective's ending to match the noun's: wrong: puella forta. Agreement is in gender, number and case, not spelling. Fortis is feminine here, so puella fortis.

ego, tū, sē: personal and reflexive pronouns Intermediate Latin · Pronouns

  • ego/mē/mihi; tū/tē/tibi; nōs/nōbīs; vōs/vōbīs.

ipse, "himself", and īdem, "the same" Intermediate Latin · Pronouns

  • ipse, ipsa, ipsum: -self, very; declined like ūnus (gen. ipsīus).
  • ipse emphasises; sē reflects back to the subject.
  • īdem, eadem, idem = is + -dem; m before d becomes n (eundem).
ipse, ipsa, ipsum
-self (emphasis); the very

adds emphasis: ipse
reflexive
refers back to the subject: sē

Watch out: Using sē for emphasis: wrong: Rēx sē vēnit. Sē is never the subject. For "the king himself came", use ipse: Rēx ipse vēnit.

hic, iste, ille: this and that Intermediate Latin · Pronouns

  • hic (this, near me), iste (that, near you), ille (that, far away).
  • hic: hic haec hoc, huius, huic, hunc hanc hoc, hōc hāc hōc.

more
multō

Watch out: Forming these regularly: wrong: magnior, wrong: bonior. They must be learned: maior, melior. Also, plūs in the singular is a noun: wrong: plūs mīlitēs for "more soldiers" is wrong; use the plural adjective plūrēs mīlitēs.

clārē, fortiter: adverbs and their comparison Intermediate Latin · Comparison

  • 1st/2nd-declension adjectives: -ē; 3rd-declension: -iter (one ending: -ter).
  • Comparative -ius; superlative -issimē.

hortor, sequor: deponent verbs Intermediate Latin · Deponent verbs

  • Deponent: passive endings, active meaning.
  • Three principal parts: hortor, hortārī, hortātus sum.
  • All passive tenses apply: hortor, hortābar, hortābor, hortātus sum …
  • Translate actively: secūtus est = he followed.

Watch out: Translating deponents as passive: wrong: The soldiers are followed for Mīlitēs sequuntur. A deponent is active in meaning: the soldiers follow. Check the dictionary entry: if the first principal part ends in -or and the third is -us sum, it's deponent.

amem, regam, sim: the present subjunctive Advanced Latin · The subjunctive

  • Indicative = fact; subjunctive = idea (wish, purpose, possibility).
  • Present subjunctive: -ē- in conjugation 1, -ā- in 2, 3 and 4.
  • sum: sim, sīs, sit, sīmus, sītis, sint.
  • In a main clause: a wish (fortis sit) or "let us" (proficīscāmur).

the mood for facts
mood sign
-ē- (1st conjugation) or -ā- (others) in the present subjunctive
sim, sīs, sit
present subjunctive of sum
statim
at once

Watch out: Reading regam or audiam as future. In the first person singular of the third and fourth conjugations, the future and the present subjunctive look the same (regam, audiam). The other persons differ: future regēs, reget; subjunctive regās, regat. Let the sentence decide.

ut, nē, quī: purpose clauses Advanced Latin · The subjunctive

  • Purpose: ut / nē / quī / quō + subjunctive.
  • nē for negative purpose, never ut nōn.
  • quō when the clause has a comparative.
  • Latin prose never shows purpose with the infinitive.
ut (+ subjunctive)
in order that, so that
nē (+ subjunctive)
so that … not, lest
quī (purpose)
a relative clause of purpose: men to find
quō (+ comparative)
so that … the more
purpose clause
says why the main action is done

Watch out: Using ut nōn for a negative purpose: wrong: ut nōn capiantur. A negative purpose takes nē: nē capiantur, so that they may not be captured.

amārem, essem: the imperfect subjunctive and the sequence of tenses Advanced Latin · The subjunctive

  • Imperfect subjunctive = present infinitive + -m, -s, -t, -mus, -tis, -nt.
  • sum: essem, essēs, esset …

present infinitive + endings: amārem
essem, essēs, esset
imperfect subjunctive of sum
primary tenses
present, future, future perfect
secondary tenses
imperfect, perfect, pluperfect
sequence of tenses
primary goes with primary, secondary with secondary

Watch out: Keeping the present subjunctive after a past main verb: wrong: Mīsit ut vāstent. A secondary (past) main verb takes a secondary subjunctive: vāstārent.

amāverim, amāvissem; indirect commands Advanced Latin · The subjunctive

  • Perfect subjunctive: perfect stem + -erim; pluperfect: + -issem.
  • Passive: participle + sim / essem.

persuādeō, persuādēre (+ dat.)
persuade
rogō, rogāre
ask
pugnō, pugnāre
fight
discēdō, discēdere, discessī

Watch out: Giving iubeō an ut clause, or imperō an infinitive. Iubeō + accusative + infinitive; imperō + dative + ut / nē + subjunctive.

possim; "I fear that …" Advanced Latin · The subjunctive

  • possum subjunctive: possim; possem; potuerim; potuissem.

fear
vereor, verērī, veritus sum
fear
nē (after fearing)
that, lest
ut (after fearing)
that … not

Watch out: Translating nē as "not" after a verb of fearing: wrong: I fear that he will not come for Timeō nē veniat. After fearing, nē = that, and ut = that not.

amāns, amātus, amātūrus, amandus: participles Advanced Latin · Participles and irregular verbs

  • Present active -ns; future active -ūrus; perfect passive -us; gerundive -ndus.
  • Present = same time; perfect = before; future = after.
  • Deponents: perfect participle active in meaning.
  • Translate with a clause: when, since, after, although, who.
present participle

perfect participle
-tus, -sus: before (passive)
future participle
-tūrus: about to
gerundive
-ndus: to be …ed
currō, currere, cucurrī
run
morātus
having delayed (moror, deponent)

Watch out: Translating every participle word for word with "-ing" or "having been": "the soldiers, having been conquered, did not turn their backs" is stiff English. Pick the clause that fits: when, since, after, although, who.

volō, nōlō, mālō; the ablative absolute Advanced Latin · Participles and irregular verbs

  • volō, vīs, vult; nōlō, nōn vīs, nōn vult; mālō, māvīs, māvult.

ablative absolute
noun + participle in the ablative, setting the scene
dux, ducis, m.
leader
pugnō, pugnāre
fight
discēdō, discēdere, discessī
leave, go away

Watch out: Putting the subject in the ablative absolute: wrong: Mīlitibus victīs fūgērunt for "the soldiers, beaten, fled". The beaten soldiers are the subject, so: Mīlitēs victī fūgērunt.

fīō; "so … that": result clauses Advanced Latin · Clauses

  • fīō, fierī, factus sum: passive of faciō; fit has a short i.
  • Result: ut / ut nōn + subjunctive, often after tam, ita, sīc, tantus.
  • Purpose negative nē; result negative ut nōn.
  • Translate results as facts.
fīō, fierī, factus sum
be made, become, happen
result clause
ut / ut nōn + subjunctive: so that, with the result that
tam
so (with adjectives and adverbs)
ita
so, in such a way (usually with verbs)
tantus, -a, -um
so great

Watch out: Translating a result clause with "might" or "in order that": wrong: so brave that the enemy might flee. A result is a fact: so brave that the enemy fled.

"The man to lead us": clauses of characteristic Advanced Latin · Clauses

  • Relative + indicative: fact. Relative + subjunctive: description (characteristic).
  • is quī, nēmō est quī, sunt quī, nihil … quod + subjunctive.
  • Making, choosing, calling: two accusatives; passive: two nominatives.

predicate accusative
second accusative after make, choose, call
creō, creāre

appellō, appellāre
call, name
cōnsul, cōnsulis, m.
consul

Watch out: Reading every subjunctive relative clause as purpose. After is, nēmō, quis, sunt, erant, a subjunctive relative usually describes: the kind of person who. Purpose relatives follow verbs of sending or choosing (mīsit quī …).

cum: when, since, although Advanced Latin · Clauses

  • cum = when (indicative if it only dates; subjunctive if it describes), since, although (subjunctive).
  • tamen in the main clause → although.
  • cum + ablative noun = with.
  • Ablative of specification: in what respect.
cum (conjunction)
when, since, although
cum (preposition)
with (+ ablative)
tamen
yet, nevertheless
ablative of specification
in what respect: corpore, in body
virtūs, virtūtis, f.
courage

Watch out: Confusing the conjunction with the preposition. cum + ablative noun = with (cum mīlitibus). cum + a clause with a verb = when / since / although.

amandī, ad urbem videndam: gerund and gerundive Advanced Latin · Participles and irregular verbs

  • Gerund: -ndī, -ndō, -ndum, -ndō; a noun.
  • Gerundive: -ndus, -a, -um; agrees with a noun; preferred with an object.
  • Purpose: ad + acc. or gen. + causā.
  • Predicate genitive: equus est Galbae.

for the sake of
ad + gerund/gerundive
to, for the purpose of
predicate genitive
equus est Galbae: the horse is Galba's
placeō, placēre (+ dat.)
please

Watch out: Keeping gerund + object after ad: wrong: ad videndum urbem. With an object, use the gerundive in agreement: ad urbem videndam.

eō; "he said that …": indirect statement Advanced Latin · Clauses

  • eō: eō, īs, it, īmus, ītis, eunt; īre.
  • Indirect statement: accusative subject + infinitive; no word for "that".
  • Present inf. = same time; perfect = earlier; future = later.
  • sē refers back to the speaker.
eō, īre, iī, itum

putō, putāre
think
sciō, scīre
know
vincō, vincere, vīcī, victus
conquer, win
nūntiō, nūntiāre
announce

Watch out: Changing the infinitive's tense after a past verb, as English does. Dīxit eum venīre uses the present infinitive for "he said he was coming" (same time). Only use the perfect infinitive for something earlier: dīxit eum vēnisse, he said he had come.

ferō; the dative with compounds; indirect questions Advanced Latin · Clauses

  • ferō, ferre, tulī, lātus: fert, ferunt; irregular in the present.
  • Compounds with ad, in, prae, inter … often take the dative.
  • Indirect question: question word + subjunctive, sequence of tenses.
  • Yes-or-no → num, whether.
ferō, ferre, tulī, lātus
bear, carry
referō, referre, rettulī, relātus
bring back; report
īnferō (+ dat.)
bring against; bellum īnferre, make war on
indirect question
question word + subjunctive after asking or knowing
rogō, rogāre
ask
num (indirect)
whether
cūr
why

Watch out: Using the indicative in an indirect question: wrong: Rogāvit quis vēnit. After a verb of asking or knowing, the question's verb is subjunctive: Rogāvit quis vēnisset.

The cases and the moods: a review Advanced Latin · Review

  • Dative of purpose, often with a dative of the person: magnō impedīmentō Gallīs.
  • Description: genitive for measurements, ablative for physical features, either for other qualities; always with an adjective.
  • Know the jobs of each case and each subjunctive use; name constructions by what they do.
dative of purpose
what something serves as: praesidiō, as a guard
double dative
purpose + person affected: impedīmentō Gallīs
genitive of description
measurements: fossa decem pedum
ablative of description

guard, garrison
impedīmentum, -ī, n.
hindrance
perterreō, perterrēre, perterruī, perterritus
terrify
maneō, manēre, mānsī
stay, remain

Watch out: Naming a construction by its look, not its job. Ut can be purpose, result or indirect command; cum can be "with", "when", "since" or "although"; an ablative can be cause, means or time. Ask what the word does in the sentence.
