Etymology
From Middle English louen, lowen (“rascal; rogue”), probably of Middle Dutch or Middle Low German origin. Compare Dutch loen (“simpleton”). Or, related to etymology 2, due to the bird's loud cry. Folk etymology associates it slang-wise with lunatic, though the latter may have influenced it; see loony.
Of North Germanic origin, from Old Norse lómr (“loon”), ultimately imitative of the bird's cry, particularly when it's in danger. Distantly related to lament, probably sharing Proto-Indo-European *leh₂- (expressive root).
Webster’s 1913
- noun A sorry fellow; a worthless person; a rogue.
- noun Any one of several aquatic, wed-footed, northern birds of the genus Urinator (formerly Colymbus), noted for their expertness in diving and swimming under water. The common loon, or great northern diver (Urinator imber, or Colymbus torquatus), and the red-throated loon or diver (U. septentrionalis), are the best known species. See Diver.
