bloodless

the word 'bloodless' is a transparent compound formed within english from its native germanic elements. the first element, 'blood', descends from the old english 'blōd', which has cognates across germanic languages and a probable proto-indo-european root meaning 'to swell, gush, or spurt'. the suffix '-less', from old english '-lēas', originally meant 'free from' or 'devoid of'. the literal combination, 'devoid of blood', logically extended to describe events without bloodshed, such as a coup or revolution. further semantic development led to figurative meanings describing a person's pale complexion or a manner lacking passion and vitality, completing the journey from a concrete physical description to an abstract characterization.

Structure: blood (red fluid in body) + less (without) blood (old english 'blōd', of germanic origin, meaning the red fluid circulating in the body); less (old english '-lēas', a suffix meaning 'devoid of, free from').
