Middle English aren, from Old English aron; see er-1 in Indo-European roots.
French, from Latin ārea, open space; see area.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Middle English aren, from Old English earun, earon ("are"), reinforced by Old Norse plural forms in er- (displacing alternative Old English sind and bēoþ), from Proto-Germanic *arun (“(they) are", originally, "(they) became”), from the third person plural preterite indicative form of *iranan (“to rise, be quick, become active”), from Proto-Indo-European *er-, *or(w)- (“to rise, lift, move”). Cognate with Old Norse erun ("(they) are"), Old English eart ("(thou) art"). More at art. (Wiktionary)
From French are. (Wiktionary)
