KK: /ˈblʌdˌɡɪltɪnəs/
The feeling of guilt that comes from having caused someone's death or shed blood.
The soldier was haunted by a sense of bloodguiltiness after the battle.
Bloodguiltiness is formed from "blood" (from Old English "blōd", meaning the red liquid that circulates in the body) and "guiltiness" (from Old English "gylt", meaning guilt or sin, combined with the suffix "-ness" which denotes a state or condition). The term refers to the state of being guilty of bloodshed or murder.
Think of 'blood' as the life force and 'guiltiness' as the state of being guilty — together, they describe the serious condition of being guilty of causing death.
