Warm, bumpy, and sweet all tell us more about how something feels or tastes, so they are adjectives. Sing and walk are action verbs, and pencil is a noun—none of them describe a noun.

Sour is one of the flavors we notice on the tongue, like a lemon. That makes it an adjective for taste, not sight or sound.

Warm tells us how the blanket feels to the touch, so it describes the noun blanket. Blanket is the thing being described, not the describing word.

Rough tells us how the rock feels when we run our fingers across it—bumpy and not smooth. That is what texture means.

Spicy is the word that describes how the taco tastes—hot and peppery. Taco is the noun, so it cannot be the adjective describing itself.

The main job of an adjective is to describe a noun, giving the reader more detail. Instead of just dog, we can say fluffy dog to paint a clearer picture.

Sticky means something clings to your fingers, like honey or tape. That is a feeling you notice through touch, which makes it a describing word.

Eat is an action verb because it names something you do with food. Adjectives describe nouns, but eat tells about an action instead.

Writers often stack several adjectives to add more detail, like a tiny, soft, gray kitten. Using extra describing words helps readers picture the noun more clearly.

Words that name things are nouns, not adjectives. Desk is a noun—an adjective would be a word like wooden or small that describes the desk.
