Spelling & Dictionary Insight
The English entry for out of the blue is 15 letters long, classified as aprep_phrase, and transcribed in the International Phonetic Alphabet as /aʊt ɒv ðə bluː/.

No frequent misspelling variants are recorded for out of the blue in our index, suggesting the orthography either follows predictable English patterns or the word is uncommon enough that typo corpora lack signal.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: Short for out of the blue sky, likening an unexpected event to lightning or rain coming suddenly from a cloudless sky. 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 out of the blue, spelled O-U-T- -O-F- -T-H-E- -B-L-U-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
