A freshwater fish, specifically a chub or dace found in European waters.
From Old French chevaine or chevayne, variant of chevesne, possibly deriving from Latin caput meaning 'head' due to the fish's distinctive large head.
Medieval fishermen had dozens of names for the humble chub depending on where they lived—chevin, chevesne, chub itself—but they all recognized the same hearty fish that still populates British rivers today and still fights hard when hooked.
