The branch of medicine concerned with diseases of the ear, nose, and throat. Otorhinolaryngology is the type of medical specialty that can frustrate a non-medical person, both in trying to pronounce the word properly and with having any idea of what it means.

The words ear, nose, and throat are quite clear; however, and that is what is meant by oto–, rhino–, and laryngo–, which are the translations of “ear”, “nose”, and “larynx" or "upper part of the windpipe”; respectively, when used in combination in various word forms.
