[THE ADJECTIVE.]
[608]. Adjectives are declined like substantives, and it has been shown already how their cases are formed. But they differ from substantives in having different forms in some of their cases to denote different genders; it is convenient therefore to put their complete declension together.
[609]. Adjective stems end in -o- and -ā-, in a consonant, or in -i-.
[610]. An accusative plural of a stem in -u-, anguimanūs, with a serpent for a hand, is once used (Lucr.). There are no adjective stems in -ē-.
[611]. Adjectives are often conveniently said to be ‘of three endings,’ ‘of two endings,’ or ‘of one ending.’
By the ‘ending’ is meant the ending of the nominative singular: thus, bonus, bona, bonum, good, and ācer, ācris, ācre, sharp, are ‘of three endings’ ([409]); brevis, breve, short, is ‘of two endings’ ([410]); and audāx, bold, is ‘of one ending’ ([410]).
[612]. Adjectives ‘of one ending’ which form a gender nominative in -s, retain the -s irrationally in the nominative and accusative neuter singular: as, N. M. and F. audāx, N. and Ac. Ne. also audāx.
