Adverbs can modify all of the following except

A) Verbs

B) Adjectives

C) other Adverbs

D) Nouns

An adverb is a term that is used to alter or succeed the meaning of an adjective, a verb, a clause, one more adverb, or any extra type of term or phrase with the exclusion of determiners and adjectives that directly modify nouns. So therefore the answer is letter d - noun.

The correct answer is D. nouns.

Adverbs cannot modify nouns - adjectives and pronouns, on the other hand, can. To modify something means to describe it, and adverbs can only do that for verbs, adjectives, and other adverbs. For example:

1. verbs: to run quickly

2. adjectives: very smart

3. other adverbs: very quickly
