Our Hunspell-derived misspelling index lists 10 documented wrong-spelling variants for o'clock, with forms such as "'oclock", "o'cclock", and "o'clcok". Each variant represents a distinct typo pattern that appears often enough in corpora to be worth flagging, 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: Shortened form of "of the clock", from Middle English of the clokke [from late 14th c.]. 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 o'clock, spelled O-'-C-L-O-C-K, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
