Resembling, containing, or related to butter; having the nature or qualities of butter; buttery.
From butyr- (from Latin butyrum, butter, from Greek bous, cow, + tyros, cheese) + -ous (adjective suffix). The root combines the literal cow-source of butter with cheese terminology.
Butyrous is a formal chemistry term, but its Latin root tells us that ancient Greeks understood butter as made from cow-cheese—a beautiful example of how different cultures' foods are connected in our deepest word roots.
