Etymology: "Oropharynxes" is the plural of "oropharynx", the part of the throat directly behind the mouth. The singular is a modern scientific coinage built from two Greek-derived pieces: "oro-", from Latin "os" (genitive "oris"), meaning mouth, and "pharynx", the throat, from Greek "pharynx". Because the first element is a combining form rather than an independent English word, the term reads as a deliberate piece of anatomical vocabulary rather than something that grew up in everyday speech. Its plural follows the regular English pattern for words ending in "-x". Plurals of "-x" nouns are usually formed with "-es", as in "box" and "boxes", and anatomical terms ending in "-nx" such as "pharynx" follow the same route, so "oropharynxes" is the ordinary form, though "oropharynges" also appears in medical writing, borrowed from the Greek plural pattern.
