What does ossification mean?
Ossification is the process of forming or becoming bone. In medical and anatomical contexts, it describes the development of bone tissue or the conversion of other tissue into bone, as in abnormal ossification around a joint or along the spine. The word also has a figurative meaning: a gradual process of becoming rigid, fixed, or resistant to change. This use often carries a negative connotation, implying that institutions, habits, or attitudes have hardened into a form that is difficult to alter. Although it can describe ordinary physical development, it is more common in specialized writing and in discussions of political or organizational inflexibility. Its vivid combination of a specific biological process and a broader image of hardening makes it useful for describing anything that becomes difficult to change.

Where does ossification come from?
Ossification derives from Latin ossificare, meaning “to turn into bone,” built from os, “bone,” and facere, “to make.” The noun ossification developed in English in the 17th century for the process of bone formation. Related English words include ossify and osseous, while cognate forms such as ossuary and osteology preserve the same Latin root.
