Early 19th century: of unknown origin; compare with slug2.

  • slug from Late Middle English:

    In medieval times a slug was a slow-moving lazy person, and over time the word came to describe any slow-moving animal or vehicle. For example, the big-game hunter William Baldwin, writing in 1863, described one of his horses as ‘an incorrigible slug’. It has been the term for a slimy snail-like creature since the early 18th century. A slug of whisky, or of lead, is probably the same word, but to slug someone is not, and is related to slog (early 19th century), and we do not know the origin of either. Sluggard is based on the rare verb slug, ‘to be lazy or slow’, which may be Scandinavian in origin and which is probably also the source of sluggish, ‘slow and lazy’.
