The act of beheading a person, usually instantly such as with a large and heavy knife or by guillotine, as a form of capital punishment. This form of capital punishment is still in use in some Arab countries, notably Saudi Arabia.
Decapitation (from Latin, caput, capitis, meaning head), or beheading, is the removal of a living organism's head. Beheading typically refers to the act of intentional decapitation, e.g., as a means of murder or execution; it may be accomplished, for example, with an axe, sword, or knife, or by means of a guillotine. Accidental decapitation can be the result of an explosion, automobile or industrial accident, improperly-administered execution by hanging or other violent injury.
