Inherited from Middle English Derby, from Old English Dēorby, of Scandinavian/North Germanic origin, from Old Norse Djúra-bý (“village of the deer”), from dýr (“deer”) + bǿr (“settlement”). Influenced by British Latin Derventio, the Roman site predating Derby, and possibly also the Celtic river name Derwent.
Often used as a modifier before another noun, such as 'derby day' or 'derby match'.
