Etymologically, the entry records: Borrowed from New Latin peroneus longus, clipping of mūsculus peroneus longus (“long peroneal muscle”). Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is peroneus longus, spelled P-E-R-O-N-E-U-S- -L-O-N-G-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
