To make into bone; to convert cartilage or fibrous tissue into bone. The skeleton initially consists mainly of cartilage which is gradually transformed into bone during development. This bone-building process is termed "ossification." Bone is "osseous" tissue. "Os" is a synonym for "bone."" The word "os" is Latin and is related to the Greek "osteon" which also means "bone."
