Question

What's the difference between a verb, adverb, and adjective?

Answer 1

A verb is a word for an action or a state of being.
An adverb is a word used to modify a verb, an adjective, or another adverb.
An adjective is a word used to describe a noun.

Explanation:

VERB
Examples of action verbs are: walk, talk, think, see, eat, find, believe, sit.
Examples of verbs that relate a state of being are: am, are, is, will, was, were.
Verbs can work together, this function is called an auxiliary or helping verb, for example:
-- I am walking.
-- We were talking.
-- I will see.

ADVERB
An adverb is used to show degree, manner, place, or time of the verb, adjective, or another adverb that it modifies.
Examples of adverbs are: very, slowly, nearly, often, never, strangely, not.
Example use of adverbs:
-- We were not talking. (modifies the verb 'were talking')
-- Today is very hot. (modifies the adjective 'hot')
-- I was walking very slowly. (modifies the adverb 'slowly')

ADJECTIVE
Most adjectives used to describe nouns have degrees:
-- Positive degree = hot, small, strange, heavy, pretty.
-- Comparative degree = hotter, smaller, stranger, heavier, prettier.
-- Superlative degree = hottest, smallest, strangest, heaviest, prettiest.
Example use of adjectives.
-- She wore a pretty dress. (describes the noun 'dress')
-- The smaller children ride a school bus. (describes the noun 'children')
-- We saw the strangest sight. (describes the noun 'sight')
