Origin of garbage
First recorded in 1400–50; of uncertain origin; Middle English garbage, gabage “discarded parts of butchered fowls; entrails of fowls used for human food”; compare with Middle English garbelage “removal of refuse from spices,” Middle English garbelure “refuse found in spices,” and Old French garbage (also jarbage ) “tax on sheaves of grain,” but the shift of sense here is unclear; see also garble, -age
