A root word is the base of a word that has no prefixes or suffixes. A prefix or suffix is a word part that is added to the beginning or end of a word to change the meaning. Common suffixes change the verb tense like -ed or -ing. Prefixes like re- change how the action is performed. For example, rewind means that it is something being winded up again as opposed to for the first time.
