Many nouns have a consonant stem in the singular, and an #-i-# stem in
the plural: see 516; most substantives in #-iē-# or #-tiē-# have a
collateral form in #-iā-# or #-tiā-# (604). Some adjectives have two
different stems: as, #hilarus#, #hilara#, #hilarum#, and #hilaris#,
#hilare#; #exanimus# and #exanimis#.
