The word traces to Proto-Germanic *laukaz (allium plant).

The leek is the national emblem of Wales, worn on St David's Day — a tradition already attested in Shakespeare's Henry V. Key roots: *laukaz (Proto-Germanic: "allium plant, leek — the ancestral Germanic word for all allium vegetables; no confirmed PIE root").
