deportee n.

"banish, transport or carry off from one country to another, especially forcibly," 1640s, from French déporter, from Latin deportare "carry off, transport, banish, exile," from de "off, away" (see de-) + portare "to carry," from PIE *prto-, suffixed form of root *per- (2) "to lead, pass over." Associated by folk etymology with portus "harbor." Related: Deported; deporting.

word-forming element in legal English (and in imitation of it), representing the Anglo-French -é ending of past participles used as nouns (compare -y (3)). 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.

Not to be confused with the French -ée that is a feminine noun ending (as in fiancée), which is from Latin -ata.
