The English entry for neo- is 4 letters long, classified as aprefix, and transcribed in the International Phonetic Alphabet as /ˈniːəʊ/. It sits outside the most-frequent rank tiers, which is often why uncommon words generate more spelling variants per reader.Wiktionary records 5 distinct senses for this headword, so context determines which meaning a reader should apply.

No misspelling variants are generated for neo- 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: From Ancient Greek prefix νεο- (neo-), from νέος (néos, “new, young”). 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 neo-, spelled N-E-O--, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
