Excess supply refers to a situation in which there is more of a product or service available in a market than there is demand for it. This leads to a surplus and can result in lower prices for the product. Synonyms for excess supply include oversupply, glut, surfeit, abundance, surplus, and redundancy. Oversupply refers to an excessive amount of a particular product or service in the market. Glut, on the other hand, refers to a surplus of something to an extent that it becomes difficult to dispose of. Surfeit denotes more of something than is necessary or desirable, while abundance indicates an ample or plentiful quantity. Surplus and redundancy indicate an excess of something beyond what is needed or used.
