The English entry for who would have thunk it is 23 letters long, classified as a phrase, and transcribed in the International Phonetic Alphabet as /ˈhuː wʊd həv ˈθʌŋk ɪt/. It sits outside the most-frequent rank tiers, which is often why uncommon words generate more spelling variants per reader.

No misspelling variants are generated for who would have thunk it in our index, suggesting the orthography follows predictable English patterns. 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: The word thunk is a humorous, nonstandard past participle of think. 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 who would have thunk it, spelled W-H-O- -W-O-U-L-D- -H-A-V-E- -T-H-U-N-K- -I-T, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
