first person meus, -a, -um     noster, -tra, -trum
second person tuus, -a, -um     uester, -tra, -trum
third person suus, -a, -um     suus, -a, -um



Comparative of Adjectives

The comparative is based on the third declension.

doctus, doctior, < doct *-yos (wise, wiser)

  masc./fem.     neuter
nom./voc. sg. doctior     doctius
acc. sg. doctiorem     doctius
gen. sg. doctioris     doctioris
dat. sg. doctiori     doctiori
abl. sg. doctiore     doctiore

acc. pl. doctiores     doctiora
gen. pl. doctiorum     doctiorum
dat. pl. doctioribus     doctioribus
abl. pl. doctioribus     doctioribus

With a complement, the comparative is constructed with an ablative:

    doctior Petro (wiser than Peter)

or the more complex construction of comparative equality:

    tam doctus est quam Petrus (he is as wise as Peter)

and:

    doctior quam Petrus (wiser than Peter)

as well as:

    doctior quam puto (wiser than I think)




Superlative of Adjectives

Most adjectives from first or second declension:

    uast-issimus, f. uastissima (most vast, widest)

Many adjectives from second declension whose stem ends in a liquid:

    pulcher-rissima, m. pulcherrimus (most beautiful, most handsome)

Few irregular adjectives having an ancient form:

    max-imus, < *mag-simus (greatest)



Notes on the Superlative

1. The superlative’s complement is expressed in Latin either using the genitive:

    Romanorum prudentissimus (the most careful of Romans)

2. ...or the ablative:

    e Romanis prudentissimus (of [all] Romans, the most careful)

    and similarly, ...

    altissima arborum or altissima ex arboribus (the tallest of trees)

Final Notes on Adjectives in Latin

1. Adjectives are frequently used as nouns:

    boni (good people)
    bonum (good [the good that we do])
    bona (goods)


2. Some adjectives are accompanied by a complement whose case is appropriate to the meaning of each adjective:

    loco multis commodis prædito, præditus + abl. ([in] an area endowed with numerous advantages)


3. Sometimes, this complement is governed by a preposition:

    res ad uitam necessarias, (things indispensable to life)
