Capitulum II — Familia Rōmāna

After the map of the Empire, you step through the front door of a house: a father, a mother, children — and slaves, because the Roman familia is the whole household, slaves included. Beneath this domestic scene the chapter installs two big mechanisms: the three genders get their names, and a new case appears, the genitive.

The three genders: masculīnum, fēminīnum, neutrum

The chapter names what you have been observing all along — and it does so in Latin: masculīnum (m), fēminīnum (f), neutrum (n). Every noun has a fixed gender, usually readable from its ending:

gender typical ending examples
masculine -us (sometimes -r) servus, dominus; vir, puer, liber
feminine -a fēmina, puella, ancilla
neuter -um oppidum, vocābulum, neutrum

Memorize the three masculines in -r: vir (man), puer (boy), liber (book). They decline like servus, but their nominative has no -us.

In passing: the book spells genetīvus, with an e — the spelling we follow throughout.

The genitive: saying whose it is

The genitive is the case of the possessor; it answers the question cuius? ("whose?") and stands next to the noun it completes:

Līvia fīlia Cornēliī est. — Livia is Cornelius's daughter. Lȳdia ancilla dominae est. — Lydia is the mistress's maidservant.

The endings of the first two declensions:

gen. singular gen. plural
1st decl. (-a) ancillae ancillārum
2nd decl. (-us, -um) servī servōrum

Two endings are ambiguous — context decides:

  • -ae = genitive singular or nominative plural: fīlia dominae ("the mistress's daughter") but dominae sunt ("they are mistresses");
  • = genitive singular or masculine nominative plural: liber puerī ("the boy's book") but puerī sunt ("they are boys").

The book also hands you an equivalence worth memorizing: magnus numerus + genitive plural ≈ multīmagnus numerus servōrum = multī servī; likewise parvus numeruspaucī.

The chapter's trap: liber, librī (short i, the book, with the e dropping out: librī, librōrum) is not līberī, līberōrum (long ī's, the children, plural only). The macrons do all the work.

quis, quae, cuius, quot: asking questions

The interrogative pronoun agrees with the expected answer:

you ask about form example
a man quis? Quis est pater puerī?
a woman quae? Quae est māter puellae?
several men quī? Quī sunt fīliī dominī?
the owner cuius? Cuius liber est?Titī.
a number quot? Quot līberī sunt?Duo.

Note the answer to cuius?: a bare genitive is enough (Titī — "Titus's"). Quot is indeclinable and calls for a numeral in reply.

meus and tuus

The possessives meus ("my") and tuus ("your") decline and agree exactly like magnus -a -um: dominus meus, domina mea, oppidum meum; Ubi est pater tuus? The possessor is the person speaking (meus) or spoken to (tuus) — but the agreement follows the noun possessed.

duo, duae, duo — trēs, tria — centum

The small numerals agree in gender:

with a masculine with a feminine with a neuter
duo puerī duae puellae duo oppida
trēs puerī trēs puellae tria oppida

Centum (100) is indeclinable: centum servī, centum ancillae, centum oppida.

-que: the enclitic "and"

-que, attached to the end of a word, links that word to the one before — it is equivalent to et placed in front:

Titus Līviaque = Titus et Līvia.

Like -ne in chapter I, -que cannot stand alone: it always attaches to the second member of the pair.

One-line takeaway: three genders (-us/-r, -a, -um); possessor in the genitive (-ae/-ārum, -ī/-ōrum); quis/quae/cuius/quot for questions; liberlīberī; X Y-que = X et Y.
