Difference between Aureole and orioleAureole means a circle of light or radiance surrounding the head or body of a representation of a deity or holy person; a halo: “The picture of the Buddha in the stained glass has a beautiful aureole surrounding the head.”
Oriole, on the other hand, is a tropical songbird; the male is usually bright orange and black: “During her travels in the Ranthambore sanctuary, she saw a beautiful oriole flitting through the trees.”
