Clavicle: The Latin word clavicula has the meaning of small key, the diminutive form of clavis (so called because of its shape). It is a loan word from the Greek kleis which means “key, collarbone.”
Rib: Has its roots in the Old English rib, and ribb of Germanic origin and further related to Dutch rib(be) as well as the German Rippe with the meaning of “a covering”, from the Proto Indo European root rebh- meaning “roof.”

Manubrium: Come from the Latin manus (hand) with the meaning of handle or haft.
Sternum: Came to English through Latin via the Greek word for chest sternon.
Sacrum: From the Latin os sacrum, which itself is a translation of Greek hieron osteon “sacred bone.” This name may originate from the fact that the sacrum was often offered up as part of animal sacrifices.

Pelvis: Has its roots in the Latin word pelvis meaning “basin” (Old Latin peluis), and ultimately from the Proto Indo European root pel- meaning “container.”

Ulna: Although the relationship may not be apparent at first glance the words ulna and elbow are etymologically related. The Old English word eln shares an Indo-European root with the Latin ulna. The Old English word for elbow was elnboga which is broken down into eln “forearm” and boga “bend, bow.” There is a older Proto Indo-European root *el- meaning “forearm, elbow.”

Tibia: The same word in Latin was used for the shinbone but also had the meaning of “pipe” or “flute,” presumably because of it’s shape.
Fibula: Comes from the Latin word fibula, which meant “clasp, buckle, brooch” probably because its shape resembled that of a fastener. Etymonline suggests that it is probable related to the Greek perone, which had this meaning. On the other hand, the Oxford English Dictionary points to a possible relationship with the Latin figere meaning “to fix,” which in turn can be traced back to a PIE root *dhigw– (“to stick, to fix”).
Calcaneus: Comes from the Latin calx, meaning heel as well as chalk. This in turn derives from the Greek χάλιξ meaning pebble or stone.
Talus: From the Latin talus meaning ankle. It is related to the Latin word taxillus, which was a small die, since dice were originally made from the anklebones of animals.
