alley n.1
mid-14c., "passage in a house; open passage between buildings; walkway in a garden," from Old French alee (13c., Modern French allée) "a path, passage, way, corridor," also "a going," from fem. of ale, past participle of aler "to go," which is of uncertain origin. It might be a contraction of Latin ambulare "to walk" (Watkins, see amble (v.)), or it might be from Gallo-Roman allari, a back-formation from Latin allatus "having been brought to" [Barnhart]. Compare sense evolution of gate.
