A misspelling magnet

The generator records 18 spelling variants around unproductive (IPA /ˌʌn.pɹəˈdʌk.tɪv/), anadjective. Corpus frequency is #25,633 among 1,433 “U” headwords. Wiktionary lists 2 senses, so context still picks the gloss.

Our generated misspelling index lists 18 likely wrong-spelling variants for unproductive, with forms such as "nuproductive", "unnproductive", and "unporductive". Each of these forms differs from the correct spelling by one small edit: a doubled letter, a dropped silent letter, or a substituted vowel. It is not paired with a close-neighbour confusable in our dataset, which usually means its spelling is distinct enough that readers don't reach for a similar-looking word instead.

Etymologically, the entry records: From un- + productive. The correct English form is unproductive, spelled U-N-P-R-O-D-U-C-T-I-V-E.
