To mix or throw into confusion; to jumble together thoroughly.
From 'be-' (Old English prefix meaning around or thoroughly) plus 'jumble' (origin uncertain, possibly from Middle English or Scandinavian roots, meaning to mix confusingly). The prefix intensifies the action of mixing.
The 'be-' prefix created hundreds of verbs in Middle and Early Modern English, many now forgotten—'bejumble' is one of the casualties, but it perfectly demonstrates how speakers once loved creating super-verbs with intensive prefixes.
