Etymology

beware = be<prefix: thoroughly> + ware<watchful>

  • be-: A prefix from Old English "bī-" (thoroughly, about), intensifying the root.
  • ware: From Old English "wær" (watchful, cautious), related to "wary" and "aware."

Etymology Origin:
"Beware" originated in Middle English as a combination of the intensifying prefix "be-" and the Old English root "ware" (vigilance). It originally meant "to be thoroughly watchful," reflecting its use in warnings. Over time, it shed its transitive usage (e.g., "beware the dog") and now primarily functions as an intransitive verb ("Beware of scams").
