Spelling & Dictionary Insight

The English entry for indigo is 6 letters long, classified as anoun, and transcribed in the International Phonetic Alphabet as /ˈɪn.dɪˌɡəʊ/. Corpus data places it at rank #19,366 in overall English word frequency, marking it as uncommon enough that many writers pause before typing it.Wiktionary records 4 distinct senses for this headword, so context determines which meaning a reader should apply.

Our Hunspell-derived misspelling index lists 8 documented wrong-spelling variants for indigo, with forms such as "idnigo", "inddigo", and "indgio". 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 also participates in 10 confusable-pair relationships, "Indo", "indio", "Indira", and more, where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: 16th century (as indico, modern spelling from the 17th century), Spanish índigo, Portuguese endego (modern índigo), or Dutch (via Portuguese) indigo, all from Latin indicum (“indigo”), from Ancient Greek ἰνδικόν (indikón, “Indian dye”), from Ἰνδία (Indía). … 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 indigo, spelled I-N-D-I-G-O, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
