What is another word for turning to bone?
Pronunciation: [tˈɜːnɪŋ tə bˈə͡ʊn] (IPA) 
"Turning to bone" is a phrase that describes a gradual change or transformation that makes something rigid, inflexible and immobile. There are several synonyms that can be used instead of "turning to bone" such as ossifying, solidifying, petrifying, or hardening. Ossifying refers to the process of bone formation, and the term is often used in reference to a once pliable tissue that has become hard as a result of calcium deposit. Solidifying and petrifying both refer to the hardening of materials such as liquids or organic matter. Hardening specifically refers to something becoming more rigid and inflexible. Ultimately, each of these words can be used to describe a similar process of change from something soft or flexible to something hard and fixed.
