First of all an adjective is a describing word. for example, "there is a big, yellow bus." the noun is "bus" and the adjectives (describing words) are "big" and "yellow". but a vivid adjective is and adjective that describes a bright color or, intese feeling. and a verb is an action word. for example, "the boy was running, walking, and jogging to win the race." the verbs (action words) are "running", "jogging", and "walking". but a vivid verb is a more detailed verb. for example, instead of walking, use strolling or scuffing. strolling is slower than walking so i suggest looking up the definition of the word you are going to use. to make the essay easier for you, maybe try taking an event from your life and try using vivid verbs (more detailed action words) and adjectives ( more detailed describing words) to write the story. i suggest a fun part of your life, like going to disneyland for the first time, or your favorite birthday party. just something fun and easy to write about. but if your really don't want to talk about an event in your life, then making up a story is your next best option. just have fun with whatever you decide to write about. i'm sure you can get it done in 200 words or more. hope this !
