goof

Perhaps from dialectal English goff (“foolish clown”), from earlier goffe, in which case further etymology is uncertain.

Perhaps from Middle English goffen (“to speak in a frivolous manner”), possibly from Old English gaf, ġegaf (“base; wanton; lewd”, adj), ġegaf (“buffoonery; scurrility”, noun), gaffetung, golfettung (“buffoonery; mockery”). Compare English dialectal gauffin (“lightheaded; foolish; giddy”), Scots gaff, gawf (“to talk loudly; babble”), Scots gaffaw (“a loud laugh”).

Alternatively, perhaps from Middle French goffe (“awkward; stupid”). Compare also Spanish gofo, Italian goffo.
