Our generated misspelling index lists 14 likely wrong-spelling variants for coefficient, with forms such as "ccoefficient", "ceofficient", and "coeffciient". 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. Our confusable-pair dataset has no match for it, which tends to mean the word is visually distinctive enough to stand on its own.

Etymologically, the entry records: From French coefficient. Coined by French mathematician François Viète. Or influenced by (New) Latin coefficient-, which is the stem of coefficiens, which is a substantivation of the present active participle of coefficio, which comes from co- and efficio. The correct English form is coefficient, spelled C-O-E-F-F-I-C-I-E-N-T.
