The word "odontonomy" is an uncommon term in English language that refers to the classification and study of teeth. Its spelling is derived from two Greek words- "odonto", meaning tooth, and "nomia", meaning knowledge or law. The correct pronunciation of this word is /ɒdɒnˈtɒnəmi/ with emphasis on the third syllable. The first syllable is pronounced as "od-on", while the second syllable is pronounced as "ton". The last syllable "mi" is pronounced as "nee."
