What are "Root Words"?A root, or root word is a word which is used to form another word. It is also called a base word. A root does not have a prefix (a letter or group of letters added to the beginning of a word) or a suffix (a letter or group of letters added to the end of a word).Root is the primary lexical unit of a word, and of a word family.For example, pure is a root.
