Etymology: Odontologist is a plain modern formation: the noun "odontology" (the study of teeth) with the agent suffix "-ist" added to name a practitioner. The base itself is built from Greek "odous" (tooth) and "-logia" (study of), and the study of teeth got its name from that combination, so the whole word is a classical compound assembled to label a specialist in dental science. The suffix has a longer pedigree than the base. "-ist" comes from Greek forms ending in "-istēs", which named people who practised or followed something, and it passed through Latin "-ista" and Old French "-iste" into Middle English before settling as a standard English ending. Its path into English shows how often a single small suffix gets reused: the same ending turns "dentist" and "biologist" into professionals, and "odontologist" joins that family.
