Words that share the same base word can look similar. But a prefix or a suffix changes the meaning of the base word. For example:

• • pack means “to put things in a container.”

• • packer means “someone who packs,” because the suffix -er means “one who.”

• • unpack means “to take things out of a container.” Explain how the meanings of the word parts add up to this definition.

Figure Out Word Meanings Work with a partner. Cover the prefix or suffix in each word. Find the base word. Uncover the prefix. What does it mean? Then put the meanings together and write the meaning of the word.
