A misspelling magnet

The generator records 7 spelling variants around impur (IPA \ɛ̃.pyʁ\), anadjective. Corpus frequency is #30,648 among 3,561 “I” headwords. Wiktionary lists 9 senses, so context still picks the gloss.

Our generated misspelling index lists 7 likely wrong-spelling variants for impur, with forms such as "immpur", "imppur", and "impru". 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 also participates in 12 confusable-pair relationships, "input", "impute", "imputer", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.

Our source data has no etymology on file for this entry, so its spelling pattern is best understood through pronunciation rather than a traceable origin. The correct French form is impur, spelled I-M-P-U-R.
