In a way that shows a lack of awareness or intention; done without knowing or realizing it.

**Unwittingly** → It is formed from "un-" (meaning not) and "witting" (from Old English *witan*, meaning to know) and the suffix "-ly" (meaning in a manner). The word "unwittingly" means in a manner that is not known or without awareness.
Think of 'not knowing' ('un-') and 'to know' ('witting') — that's why unwittingly means doing something without awareness.
