Leonine By Deane Barker • June 6, 2023 • Definition: resembling a lion; powerful, majestic, like a lion This seems to be a compliment used to describe something that embodies all the positive qualities of a lion. “Leo” is Latin for lion, but I couldn’t find any references to this being used to discuss actual lions. It seems to only be used to relate other things to the qualities of a lion. Why I Looked It Up From eurostorm: Elise had never seen her leonine brother this vulnerable before.
