20 Common GED Vocabulary Words You Should Know

One of the easiest ways to raise your overall score on the GED is to improve your vocabulary. “But the GED only has a few vocab questions,” you might say. And you’re right, there is no specific vocab test on the GED, although you will see a few word usage questions sprinkled throughout the Reasoning Through Language Arts Section.

So why is vocabulary so important to your GED score?

Basically, the more words you know the more likely you are to understand what each question is asking. No matter how good you are at Math, Social Sciences, or Language Arts, it’ll be very hard to get the right answers if you don’t fully understand the questions.

To help you out, here’s a list of 20 important words that you’re likely to see in all five sections of the GED.

GED Vocabulary Words

Maybe you know all of these words already, maybe you don’t. Maybe you thought you knew these words, but you just want to double check now that the chance to finally say goodbye to high school is on the line.

The following definitions come from the Merriam-Webster Learner’s Dictionary, which defines words as clearly and simply as possible. Between each word and its definition you will see a letter (or letters) in parenthesis. These are the abbreviated versions of each word’s part of speech.

A word’s part of speech tells you about how the word is used. In this vocabulary list you will see three different parts of speech: Verbs (abbreviated as “v.”), nouns (abbreviated as “n.”), and adjectives (abbreviated as “adj.”). Nouns are words for people, places, or things. Verbs are words for actions. Adjectives are words that describe nouns.

After each part of speech is the word’s definition, followed by an example of how to use the GED vocabulary word in a sentence.
