25 Words That Are Their Own Opposites

Trim as a verb predates the noun, but it can also mean either adding or taking away. Arising from an Old English word meaning ‘to make firm or strong; to settle, arrange,’ “trim” came to mean ‘to prepare, make ready.’ Depending on who or what was being readied, it could mean either of two contradictory things: ‘to decorate something with ribbons, laces, or the like to give it a finished appearance’ or ‘to cut off the outgrowths or irregularities of.’ And the context doesn’t always make it clear. If you’re trimming the tree are you using tinsel or a chain saw?
