What is it called when you say a word but mean something else?
Could you clarify what is being referred to in the paragraph? Are you asking about a linguistic phenomenon where a person says one thing but intends to convey a different meaning? If so, that could be described as a form of "verbal irony," "sarcasm," "innuendo," or "figurative language." It's when someone intentionally uses words to convey a meaning that is different from the literal interpretation of those words. It's a common rhetorical device used for emphasis, humor, or to suggest a hidden meaning. Is this what you were asking about?
