blood-filled

the compound adjective 'blood-filled' is a transparent modern english formation. its first element, 'blood', descends from the old english noun 'blōd', a term of common germanic lineage whose ultimate proto-indo-european root is uncertain but likely related to life force. the second element derives from the past participle of the verb 'fill', from old english 'fyllan', meaning to make full, which traces back to the proto-germanic 'fullijaną' and ultimately to the pie root 'pelh₁-' (to fill). the compound logically and literally describes a state or container made full with blood, directly combining the core meanings of its constituent morphemes without significant semantic shift.

Structure: blood (fluid) + filled (made full of) blood (old english 'blōd', meaning the red fluid in the body, of germanic origin); filled (past participle of the verb 'fill', from old english 'fyllan', meaning to make full, of germanic origin).
