Here is a worksheet on the Greek word roots trop/o and -tropy. This is a complicated pair: they mean turning, changing, figure of speech, and responding to a stimulus. A lot of the words in English that grow from this root are abstract and science related–one of them, of course, is trope, which literally means “a word or expression used in a figurative sense: FIGURE OF SPEECH,” and has happily turned up in the American vernacular.
