Morphology

Chelonidae = chelon + idae

A Latinized taxonomic formation: the combining form 'chelon-' is not a productive standalone English word and the suffix '-idae' is a scientific family ending, so the meaning 'family of turtles' is not derivable by an average learner from common English vocabulary.

Etymology

Chelonidae comes from the old Greek root chelon meaning 'tortoise' or 'sea turtle', and the ending -idae shows a family or group of animals. So Chelonidae literally means 'the turtle family', which is why it names the group of large marine turtles like the green and hawksbill.
