A misspelling magnet

The generator records 10 spelling variants around radical (IPA /Rɐ.di.ˈkaɫ/), anadjective. Corpus frequency is #5,040 among 963 “R” headwords. Wiktionary lists 6 senses, so context still picks the gloss.

Our generated misspelling index lists 10 likely wrong-spelling variants for radical, with forms such as "ardical", "radcial", and "raddical". 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 also participates in 3 confusable-pair relationships, "racial", "radiação", "radicado", a pairing that trips writers up because the two words share enough sound or shape to blur together.
