A person who makes an allegation or claim about something.
From the verb 'allege' plus the agent suffix '-er,' which comes from Old English and Latin, used to create a noun for a person who performs an action.
Like 'allegator,' this is a real English word that shows how we can turn almost any verb into a person-noun by adding '-er'—think 'teacher,' 'singer,' 'runner.' It's one of English's most productive word-building patterns.
