Etymology: Dentin is a technical coinage, and its history is plain. It comes from French "dentine," which was formed from Latin "dens," meaning "tooth," the same root that gives English words like dental and dentist. The French term was then carried into English, where it names the dense, bony tissue that makes up most of a tooth's bulk. The ending is the interesting part. The "-in" or "-ine" suffix is a common chemical-style ending, used to name substances and materials, so the word reads as if it were the name of a compound. Dentin is not a chemical in the usual sense, but the naming pattern treats the tissue as a distinct material, one that sits beneath the enamel and gives a tooth most of its structure.

Synonyms: tooth substance, dental tissue, calcified tissue, enamel, pulp
