One who accuses; an accuser (a less common variant of 'accuser').
From Latin accusor, from accusare (to accuse). This is a direct Latin borrowing that parallels the English 'accuser,' with the same root but a different suffix pattern.
While 'accusor' is quite rare in modern English, it shows up in legal Latin phrases and historical documents, reminding us that English legal terminology is deeply layered with Latin terms from different time periods.
