Corpus data places it at rank #39,268 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.

Our generated misspelling index lists 11 likely wrong-spelling variants for Cthulhu, with forms such as "ccthulhu", "chtulhu", and "cthhulhu". 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: Invented in 1926 by H.P. Lovecraft for his short story The Call of Cthulhu. Possibly based on chthonic (“dwelling under the earth”). 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 Cthulhu, spelled C-T-H-U-L-H-U, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
