behead

the verb 'behead' is a formation from old english, combining the prefix 'be-' and the noun 'head'. the old english prefix 'be-' (from proto-germanic bi-) often conveyed a sense of 'about' or 'around', and when used to form verbs from nouns, it could imply 'to affect with' or 'to provide with'. in the case of 'behead', the literal sense is 'to affect someone with regard to the head', specifically to remove it. this construction follows a common germanic pattern for creating verbs of action. the word's meaning has remained remarkably consistent from its old english origins to modern usage, specifically denoting the act of decapitation.

Structure: be + head be- (old english, a prefix forming verbs with a sense of 'around, about, thoroughly, to make') + head (old english, the upper part of the human body containing the brain, eyes, etc.)
