Corpus data places it at rank #15,872 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.Wiktionary records 6 distinct senses for this headword, so context determines which meaning a reader should apply.
Our Hunspell-derived misspelling index lists 10 documented wrong-spelling variants for octopus, with forms such as "cotopus", "occtopus", and "ocotpus". 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: From Latin octōpūs, from Ancient Greek ὀκτώπους (oktṓpous), from ὀκτώ (oktṓ, “eight”) + πούς (poús, “foot”). Piecewise doublet of octopod and octopede. 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 octopus, spelled O-C-T-O-P-U-S, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
