Etymology

behave = be<thoroughly> + have<hold>

  • be (prefix): From Old English bī-, meaning "thoroughly" or "about," intensifying the action.
  • have (root): From Old English habban, meaning "to hold" or "to possess."

Etymology Origin:
The word "behave" originated in Middle English as behaven, combining the intensifying prefix be- with haven (a variant of have). It originally meant "to hold oneself in a particular way," later narrowing to "conduct oneself properly." The logic reflects controlling or "holding" one's actions (e.g., behave yourself).
