The compound adjective 'star-nosed' is a modern descriptive term from the field of zoology. Its first element, 'star', originates from the Proto-Germanic 'sternǭ', which itself derives from the Proto-Indo-European root 'h₂stḗr', meaning 'star'. The second element, 'nosed', combines the noun 'nose'—from Proto-Germanic 'nusō'—with the adjectival suffix '-ed', indicating possession. The term was coined to literally describe the unique physical characteristic of the star-nosed mole (Condylura cristata), whose snout is surrounded by 22 pink, fleshy, mobile tentacles arranged in a star-like pattern, used for exceptional tactile sensing.
