Focus on Vocabulary: Use Word Parts

Many English words are made up of parts. Often you can figure out a word’s meaning by looking at the parts.

EXAMPLES

The prefix mis- means “wrong.”The suffix -ion means “state of.”
mis- prefix+place base word= misplaceperfect base Word+-ion suffix= perfection
Misplace means “put in the wrong place.”Perfection means the “state of being perfect.”

Sometimes two base words combine to make a new compound word.

tooth + brush = toothbrush

How the Strategy Works

When you read, use word parts to figure out a word you don’t know.

  • 1. Look closely at the word to see if you know any of the parts. If you see two base words, think about the meaning of each one.

  • 2. Do you see a prefix or a suffix? If yes, cover it.misuse
  • 3. Think about the meaning of the base word.

  • 4. Uncover the prefix or suffix, and think about its meaning.

  • 5. Put the meanings of the word parts together to understand the whole word. Be sure the meaning makes sense in the text.

Use the strategy to figure out the meaning of each underlined word.
