Do latin adverbs have cases

Answer 1

Latin adverbs do not have cases; they do not decline, but the have degrees and gender and so must agree with the noun just like an adjective does. Their degree is determined, like nouns and verbs by the word endings.

The three degrees are positive, comparative, and superlative with each degree more intense than its predecessor.

Consider:

pulcher, pulchra, pulchrum = beautiful, (masc. fem. neuter ) positive degree

pulchior, pulchrius ______ = more beautiful comparative

pulchissimus, pulchirissima, pulchrissimum - most beautiful superlative

So if I want to say: I am beautiful. I write, sum pulcher. But if I want to say to a girl, You are the most beautiful, I have to write Tu es pulchrissimabecause that is the feminine form of the superlative degree of the adverb. By the same token if I need to say, He is the more beautiful, I have to write, is est pulchior because is the the relative pronoun meaning "he" and pulchrior is the masculine form of the comparative adverb. Es, is the 3rd person singular form of the indicative form of sum, meaning "he/she/it/ is".
