Write 10 verbs, noun, and adjectives in the passage.

First, you need to know how to identify verbs, nouns, and adjectives.

Verbs are action words. If someone is doing something, whatever they're doing is an action. Most verbs end in "ed" or "ing."

Nouns are people, places, things, or ideas, and can be singular or plural.

Adjectives describe things, like the purple dinosaur, the lively children, or the French woman (purple, lively, and French are adjectives, because they describe the dinosaur, children, and woman, respectively). If you're unsure as to whether it's an adjective or not, ask yourself if it gives you more details. For example, if a sentence says "three people," then "three" is the adjective, because it gives you more details than just saying "people."
