Is this is a verb or noun?

Answer 1

The word 'this' is not a verb or a noun.

The word 'this' is a pronoun, an adjective, and an adverb.

The pronoun 'this' is a demonstrative pronoun, a word that takes the place of a noun indicating near or far in place or time.

The demonstrative pronouns are this, that, these, those.

example: This is mom's favorite movie.

The adjective 'this' is placed before a noun to describe that noun.

example: This movie is mom's favorite.

The adverb 'this' modifies a verb, an adjective, or another adverb.

example: I didn't know the movie was this long.
