Some roots form whole words by themselves. For example: audio means "sound" or "hearing."
Although these roots form words in and of themselves, you can also combine them with other word elements (like prefixes and suffixes) to make new words, as in the following: audiologist
( a person who checks your hearing)

Some roots must be combined with other word elements to form words.
Prefixes and suffixes alter or refine a word's meaning . For example, the word means "able to be heard."
With the prefix becomes in-, inaudible, audible the word which means "unable to be heard."

A word can contain more than one root. For example,
