Etymologically, the entry records: From the name of Swiss mathematician Jakob Bernoulli. 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 lemniscate of Bernoulli, spelled L-E-M-N-I-S-C-A-T-E- -O-F- -B-E-R-N-O-U-L-L-I, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
