The term METAPHORS' RELATIVES refers to the word SIMILES, which is a seven-letter word. Similes are figures of speech that compare two different things using the words 'LIKE' or 'AS'. They are often used to make descriptions more vivid and interesting. Similes are closely related to metaphors, which are also figures of speech that compare two different things, but without using the words 'LIKE' or 'AS'.
