As feline is to cats and bovine is to pigs, aquiline is to eagles. Really. In fact, it’s almost always used to describe someone’s nose, as in one that is curved or bent, having a prominent bridge. If you hear someone describing another as having a “Roman nose,” it’s aquiline.
EXAMPLE: Wendy knew why her clients refused to part with this one particular sculpture even though it was irreparably damaged and aesthetically questionable: the statue’s aquiline nose reminded them of their eldest son, who had recently passed away from cancer.
