A misspelling magnet

The generator records 17 spelling variants around unchallenged, anadjective. Corpus frequency is #34,331 among 1,433 “U” headwords. Wiktionary lists 3 senses, so context still picks the gloss.

Our generated misspelling index lists 17 likely wrong-spelling variants for unchallenged, with forms such as "nuchallenged", "ucnhallenged", and "uncahllenged". 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. 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.
