TIPSThe basic part of any word is the root; to it, you can add a prefix at the beginning and/or a suffix at the end to change the meaning. For example, in the word "unflattering," the root is simply "flatter," while the prefix "un-" makes the word negative, and the suffix "-ing" changes it from a verb into an adjective (specifically, a participle).
