The noun rebuttal means an instance of rebutting evidence or an accusation (especially in a legal suit).

Synonyms are contradiction, disproving, refutation, or denial.

The word origins from Old French reboter (c. 1300) and means “to thrust back” (re- “back” and boter “to thrust, hit”). The word developed to Rebutment (1590s) and rebutter (1530s, in law).
