the.com/allegation

means A statement asserting someone did something wrong, made without proof it's true.

from From Latin allegare, 'to send forth, dispatch, or cite as evidence' — built from ad- ('to') plus legare ('to send on a commission, depute'). In Roman legal usage it meant bringing forth a claim or excuse before a court. The word entered English through Old French in the 1400s already wearing legal robes, its sense narrowing over time to mean an assertion still waiting — maybe forever — on proof.
