Behind; at or toward the rear; in or toward the background (archaic word mostly found in medieval texts).
From Old English and Middle English 'ar(e)re,' related to 'rear.' This word was common in Middle English but was gradually replaced by 'rear' and 'behind' through the 14th-16th centuries.
Medieval writers loved 'arere' for its poetic quality—nowadays it sounds like something Chaucer would write, which is probably why it disappeared once English simplified its vocabulary!
