Corpus data places it at rank #39,091 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.

Our generated misspelling index lists 12 likely wrong-spelling variants for sinkhole, with forms such as "isnkhole", "siknhole", and "sinhkole". Each variant is a distinct typo pattern an edit-distance generator flags, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution. 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 Middle English sinkehole, sinkeholl, equivalent to sink + hole. 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 sinkhole, spelled S-I-N-K-H-O-L-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
