Prefixes: Read & Respond

A prefix is a letter or group of letters placed before the beginning of a word that can change the word's meaning. Sometimes prefixes are separated from the word with a hypen, and sometimes they are not. Sometimes different prefixes can have the same meaning. When you can identify the prefix of a word, you can make a strong educated guess about the word's meaning.

According to the text, a prefix can ...

• be found at the end of a word

• help reader know if a word is important or not

• be found in the middle of a word

• changes a word's meaning

There are a lot of prefixes that means "not". These include the prefixes non- and un-. When either of them come at the beginning of another word, the meaning will be the opposite of the root word. For example something unusual doesn't happen very often, or not usually. A nontraditional school is not traditional.
