rebut (v.)

c. 1300, rebouten, "to thrust back," from Old French reboter, rebuter "to thrust back," from re- "back" (see re-) + boter "to strike, push," from a Germanic source (from Proto-Germanic buttan, from PIE root *bhau- "to strike").

Also in Middle English "assail (someone) with violent language, rebuke" (c. 1300); "repel in battle, repulse" (mid-14c.). The legalese sense of "try to disprove, refute by evidence or argument, bring counter-argument against" is attested by 1817. Related: Rebutted; rebutting.
