a suffix forming from transitive verbs nouns which denote a person who is the object or beneficiary of the act specified by the verb (addressee; employee; grantee); recent formations now also mark the performer of an act, with the base being an intransitive verb (escapee; returnee; standee) or, less frequently, a transitive verb (attendee) or another part of speech (absentee; refugee).
in legal English (and in imitation of it), represents the Anglo-Fr. -é ending of pps. used as nouns. As these sometimes were coupled with agent nouns in -or, the two suffixes came to be used as a pair to denote the initiator and the recipient of an action.
