Meaningless → It is formed from "mean" (from Old English *mænan*, meaning to signify or intend) and "-less" (meaning without). The word "meaningless" describes something that is without significance or purpose.
Think of something that has no 'significance' ('mean') and is 'without' ('-less') that significance — that's why it is called meaningless.
