A misspelling magnet

The generator records 9 spelling variants around Ontario (IPA /ɒnˈtɛə.ɹi.əʊ/), aproper noun. Corpus frequency is #5,068 among 1,431 “O” headwords. Wiktionary lists 14 senses, so context still picks the gloss.

Our generated misspelling index lists 9 likely wrong-spelling variants for Ontario, with forms such as "notario", "onatrio", and "onntario". Every one of these variants traces to a single-character edit -- an added or dropped letter, a swapped consonant, or a vowel swap -- the kind of slip a spell-checker is built to catch. This headword has no recorded confusable partner, which usually means its spelling is distinct enough that readers don't reach for a similar-looking word instead.

Etymologically, the entry records: Probably from Wyandot ontari꞉io (literally “great lake”). If so, ultimately from Proto-North Iroquoian *-õtaɹeʔ and Proto-Iroquoian * -õːtaɹiʔ. The correct English form is Ontario, spelled O-N-T-A-R-I-O.
