Etymology: "Acrodont" is a plain technical coinage built from two Greek elements. The first, "akron", means "highest" or "extremity", giving "acr-" in compounds, and the second is "-odont", from Greek "odous" meaning "tooth". Put together, the name describes exactly what the anatomy shows: teeth attached to the top edge of the jawbone rather than lodged in individual sockets. The word belongs to the vocabulary of reptile anatomy, where it names a tooth arrangement found in some lizards, such as agamids and chameleons. Because the term was built from classical roots to label a structure that naturalists had described, it is a modern scientific formation rather than a word that ancient Greeks would have recognised. Its Greek parts are ancient, but the combined term was made for the purpose of classification.
