Adverbs as Particles: Adverbs, prepostions, conjunctions, and interjections are called particles. Adverbs in Latin, as in English, modify other words in the sentence, especially verbs. Adverbs also modify adjectives and other adverbs. In English, the ending "-ly," added to an adjective, makes it easy to identify many adverbs: He walked slowly - where slowly modifies the word walked, and where slow is the adjective.
Regular Formations of Adverbs from Adjectives:
In Latin, some adverbs are formed by adding an ending to an adjective.For first and second declension adjectives, a long -e replaces the ending. Instead of the adjective carus, -a, -um (dear), the adverb is care. To adjectives from the third declension, ter is added. From the adjective fortis (brave), the adverb form is fortiter. The neuter accusative of some adjectives is also the adverb. Multum (many) becomes multum (much) as an adverb. The formation of other adverbs is more complicated.
In Latin, some adverbs are formed by adding an ending to an adjective.

Comparison of Adverbs: To form the comparative of an adverb (e.g. slower instead of slowly), take the neuter accusative of the adjectival form. There are also irregular comparative forms. The superlative is formed from the superlative of the adjective, ending in -e.
