Interlingua Grammar - Adverbs

Adverbs

There are two types of adverbs, primary and secondary. Primary adverbs are a closed class of grammatical operators, such as quasi, 'almost'; jam, 'already'; and totevia, 'anyway'. Secondary adverbs are an open class derived from corresponding adjectives by adding the suffix -mente (-amente after final -c).

felice 'happy' → felicemente 'happily'

magic 'magical' → magicamente 'magically'

A few common adverbs have optional short forms in -o.

sol 'alone' → solo or solmente 'only'

Like adjectives, adverbs use plus and minus to express the comparative and le plus and le minus to express the superlative.

Illa canta plus bellemente que illa parla. 'She sings more beautifully than she speaks.'

Le gepardo curre le plus rapide de omne animales. 'The cheetah runs the fastest of all animals.'

The adverbs equivalent to bon, 'good' and mal, 'bad' have optional irregular forms.

bonmente → plus bonmente → le plus bonmente		or		ben → plus ben → le plus ben		or		ben → melio → optimo
malmente → plus malmente→ le plus malmente		or		mal → plus mal → le plus mal		or		mal → pejo → pessimo
