A misspelling magnet

The generator records 16 spelling variants around combustion (IPA /kəmˈbʌs.t͡ʃən/), anoun. Corpus frequency is #13,487 among 43,570 “C” headwords. Wiktionary lists 4 senses, so context still picks the gloss.

Our generated misspelling index lists 16 likely wrong-spelling variants for combustion, with forms such as "ccombustion", "cmobustion", and "cobmustion". Each of these forms differs from the correct spelling by one small edit: a doubled letter, a dropped silent letter, or a substituted vowel. Our confusable-pair dataset has no match for it, which usually means its spelling is distinct enough that readers don't reach for a similar-looking word instead.

Etymologically, the entry records: From Old French combustion, from Latin combustio, from comburere (“to burn”), itself from the intensifying prefix com- + the root burere (a faulty sep. of amburere "to burn around", itself from ambi- + urere "to burn, singe"); equivalent to combust + -ion. The correct English form is combustion, spelled C-O-M-B-U-S-T-I-O-N.
