Etymology: The jailer's title is older than the prison system it serves. It comes from Middle English "warder", which may partly continue Old English "weardere", meaning one who holds a country or an inhabitant, and it traces back to a Proto-West Germanic root "*wardārī" meaning guard, watchman or lookout. The noun is built from "ward", meaning to guard or watch over, plus the agent suffix "-er", so a warder is literally one who wards. The sense of a guard in charge of prisoners is not the original one. The word first named anyone who kept watch or looked after something, and its cousins in other Germanic languages still carry that broad sense. Dutch "waarder" means an inspector, and German "Wärter" covers a guard, keeper or attendant, so the prison job is one specialisation among many.
