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. By adding prefixes and suffixes, the following words could be made: impure, purity, pureness. Similarly, play and move are root words. By adding prefixes and suffixes, the following words could be made: plays, played, playing, player | moving, movement, moved, movable, mover, movingly. In this book, I have given the most common Greek and Latin roots which are used in English language.
