A misspelling magnet

The generator records 7 spelling variants around casual (IPA /ˈkaʒ(uː)əl/), anadjective. Corpus frequency is #4,832 among 5,599 “C” headwords. Wiktionary lists 7 senses, so context still picks the gloss.

Our generated misspelling index lists 7 likely wrong-spelling variants for casual, with forms such as "acsual", "casaul", and "cassual". 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 14 confusable-pair relationships, "causal", "caudal", "costal", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: From Middle French casuel, from Late Latin cāsuālis (“happening by chance”), from Latin cāsus (“event”) (English case), from cadere (“to fall”) (whence English cadence). The correct English form is casual, spelled C-A-S-U-A-L.
