Allegedly

According to what has been stated but without proof; used to indicate that something is claimed to be true but has not been verified.

Formed from 'alleged' plus '-ly,' with 'allege' coming from Latin 'allegare,' meaning 'to dispatch on a mission' or 'to cite in support.' The word combines 'ad-' (to) and 'legare' (to send). In legal contexts, it evolved to mean 'to assert without proof,' reflecting the formal process of making claims that must be proven.
