Special Declension Adjectives
There is a small group of adjectives in Latin that follow a special declension. Their irregularities are very similar to the majority of new forms presented here.
Table 13-11 Declension of the Special Adjective tō tus, tō ta, tō tum
The most obvious difference from regular first/second declension adjectives (and most obvious similarity to the adjectives in this chapter) is in the genitive singular (-ī us) and the dative singular (-ī).
The adjectives that fall into this category are:
ū llus, -a, -um (any)
nū llus, -a, -um (no, none)
uter, utra, utrum (either [of two])
uterque, utraque, utrumque (each [of two])
neuter, neutra, neutrum (neither [of two])
sī lus, -a, -um (only, alone)
tī tus, -a, -um (whole)
alius, -a, -um (another [of an infinite set])
alter, altera, alterum (the other [of two])
