Etymology: "Calcaneal" is a straightforward adjective built from a Latin noun and an English suffix. The noun "calcaneus" is the Latin name for the heel bone, and it is itself a learned formation from "calx," the Latin word for heel. Its ending, "-aneus," is a Latin adjectival suffix, which is why the word looks as if it might be derived from something longer than it is. Anatomists in English adopted the Latin noun directly, and the adjective was then made in the ordinary way by adding the English suffix "-al" to it, giving the sense "of or relating to the calcaneus." The word is a good example of how anatomy borrowed Latin terms and then extended them with English grammar. Because the noun was already fixed in medical Latin, speakers needed only a simple suffix to turn the bone's name into a descriptive term for the parts around it, such as a calcaneal tendon or a calcaneal fracture.
