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

nom./voc. pl.  doctiores       doctiora
acc. pl.       doctiores       doctiora
gen. pl.       doctiorum       doctiorum
dat. 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)
