The condition of not being necessary or required; a situation where something is superfluous or excessive.

Needlessness → It is formed from "need" (from Old English *nēod*, meaning necessity or requirement) and "-less" (meaning without). The word "needlessness" refers to the state of being without necessity or requirement.
Think of being 'without' ('-less') something that is 'necessary' ('need'). This helps you remember that 'needlessness' means the absence of necessity.
