the viking name "djúra-bý", recorded in old english as "deoraby", means "village of the deer". however, the origin of the name 'derby' has had multiple influences; a variation of the original roman name 'derventio' with pronunciation of the letter 'v' as 'b', becoming derbentio, and later derby, along with a link to the river derwent – from the celtic meaning "valley thick with oaks" – which flows through the city, triggering a shortened version of "derwent by", meaning 'derwent settlement'.
