Etymologically, the entry records: Borrowed from Late Latin perinaeum, from Ancient Greek περίναιον (perínaion, “space between the anus and scrotum”), from Ancient Greek περίνεος, περίνεοι (períneos, períneoi, “male genitals”), itself from earlier Ancient Greek περίς (perís, “penis”) through… 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 perineum, spelled P-E-R-I-N-E-U-M, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
