Etymology: "Eburnations" is the plural of "eburnation," a medical term for abnormal ivory-like hardening of bone or tooth tissue. The plural form simply refers to several such patches, and the noun itself is the thing to trace. The root lies in Latin "ebur," meaning ivory, which gave rise to the adjective "eburnus," meaning "of ivory." From that adjective came the verb "eburnate," to make something ivory-like, and the noun "eburnation" was formed from it with the suffix "-ion," a common Latin-derived ending for nouns of process or result. Medical writers took the sense of a bone or tooth that has come to resemble polished ivory and applied it to these degenerative changes, which is why the word describes a condition rather than a material.
