ossify in Context

Did You Know?
The skeletons of mammals originate as soft cartilage that gradually transforms into hard bone (in humans, the process begins in the womb and continues until late adolescence). This bone-building process has been called ossification since the late 17th century, and the verb ossify arrived soon after the noun. Both terms have come to refer to figurative types of hardening, such as that of the heart, mind, or soul. The words come from the Latin root os, meaning "bone." Os has also entered English as a synonym of bone in scientific contexts.
