Containing, made of, or relating to albumin (a protein found in egg white, blood, and other body tissues).
From Latin 'albumen' (white of egg) + suffix '-ous' (full of, characterized by). The word has been used in English since at least the early 1800s.
When scientists first observed egg white, they named the protein 'albumin' because it's literally the white part—then made an adjective by just adding '-ous,' which is lazy but effective!
