Adjectives VS Adverbs

Adverbs modify verbs

Adjectives modify nouns.

PS. Adverbs can also modify adjectives, and other adverbs.

If the word being modified is a noun then the modifier is an adjective.

If the word being modified is a modifier or verb, you've got an adverb on your hands.

Pro tip- put the unidentified word into the following sentence: “he/she/it is very _____”. If it makes sense, your mystery word is an adjective.

If you can use it to modify a person, “kiki is lovely” its an adjective. “Kiki is skillfully” does not work, BUT if you try “Kiki builds skillfully”, the word being modified is “builds” which is a verb so you've got an adverb.
