-coccyx a cuckoo Greek (coccy, -g, =x, -z) stem coccyg-; the nominative singular form is coccyx; the cuckoo was named for its call

A single Greek compound noun used as a genus name (treated as Latin feminine by convention). The head noun is coccyx (cuckoo), qualified by the combining form geo- (earth). The name is a noun in apposition describing a ground-dwelling member of the cuckoo family Cuculidae. It was coined by Wagler (1831) for the roadrunner, which—unlike most cuckoos—is highly terrestrial.

  • jee-oh-KOK-siks Penult rule 5: the penult vowel 'o' in '-coc-' is short but is followed by two consonants (cc), so the penult is stressed.

The segment -coccyx could superficially suggest cocc- (berry) + -yx, but the dictionary entry coccy, -g, =x confirms it is the single root for 'cuckoo', making the earth-cuckoo reading unambiguous.

The Greek word κόκκυξ (kokkyx) meant 'cuckoo' (named onomatopoetically for its call) and also gave rise to the anatomical term 'coccyx' (the tailbone, which resembles a cuckoo's bill). Here it is used in its original ornithological sense. Geococcyx is the genus of the Greater Roadrunner (Geococcyx californianus) and the Lesser Roadrunner (Geococcyx velox), both terrestrial members of the family Cuculidae.
