To behead anybody, caput alicujus praecidere (with the sword; it would be wrong to say caput cervicibus abscidere, unless the person is first strangled, Cic., Phil., ii., 2: cervicibus fractis caput abscidit): securi ferire, or percutare (with the axe, as the instrument used by the executioner): decollare (as a general term, post-Augustan, Sen., and Suet., and even then rejected from the more elevated style).
