Covered or stained with blood; having blood on something.
From Middle English 'be-' prefix meaning 'to cover or make' combined with 'blooded' (past participle of blood). The 'be-' prefix was productive in Old English for creating verbs meaning to cover or affect with something.
This word shows how English used 'be-' as a productive prefix to quickly create descriptive words—you could theoretically 'be-' almost any noun to mean 'covered in' that thing. This creative verbal alchemy is why English has such flexibility compared to more rigid languages.
