Our Hunspell-derived misspelling index lists 15 documented wrong-spelling variants for conjecture, with forms such as "cconjecture", "cnojecture", and "cojnecture". 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 Old French, from Latin coniectūra (“a guess”), from coniectus, perfect passive participle of cōniciō (“throw or cast together; guess”), from con- (“together”) + iaciō (“throw, hurl”); see jet. Compare adjective, eject, inject, project, reject, subject,… 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 conjecture, spelled C-O-N-J-E-C-T-U-R-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
