beheaded

The word 'beheaded' is a layered construction from Old English. The core noun 'head' (from Proto-Germanic haubudą, ultimately from Proto-Indo-European káput-) provides the literal object of the action. The prefix 'be-' (from Proto-Germanic bi-) was a highly productive verb-forming element that could add a sense of "all around" or "to affect with," effectively turning the noun into a verb meaning "to affect with regard to the head." The suffix '-ed' then marks the action as completed, forming the past tense and past participle. Thus, the literal morphemic logic "to cause to be head-affected" evolved specifically into the grimly precise modern meaning of having undergone decapitation.
