Etymologically, the entry records: From Middle English rennet, from Old English *rynnet, *ġerynnet, from Proto-West Germanic *garunniþu (“coagulation, curdling, rennet”), cognate with Old Saxon girunnida (“a running together, coagulation”), Old High German girunnida (“rennet, coagulation”), … 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 rennet, spelled R-E-N-N-E-T, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
