Adverbs
Detailed information and declension tables can be found at Latin declension.
Adverbs modify verbs, adjectives, and other adverbs by indicating time–place, or manner. Latin adverbs are indeclinable. Like adjectives, adverbs have positive, comparative, and superlative forms.
The positive form of an adverb can be formed from an adjective by appending an adverbial suffix to the base, typically -e, -er, -iter, -itus, more rarely -o, or -um. Contrast the adjective clarus, -a, -um, which means bright, to the adverb clare, which means brightly.
The comparative form of an adverb, formed from third declension adjectives, is extremely simple. It is the same as the neuter nominative singular form of a comparative adjective and it usually ends in -ius. Instead of the adjective clarior, which mean brighter, the adverb is clarius, which means more brightly.
The superlative form as well is extremely simple. It has exactly the same base as the superlative adjective and it always ends in a long -e. Instead of the adjective clarissimus, which mean brightest, the adverb is clarissime, which means most brightly.
