No misspelling variants are generated for regular black hole in our index, suggesting the orthography follows predictable English patterns. It is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: From regular (“continuous”) + black hole (“region enclosed by an event horizon”). From having a spacetime formulation that is without discontinuities, that is, regular. 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 regular black hole, spelled R-E-G-U-L-A-R- -B-L-A-C-K- -H-O-L-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
