A misspelling magnet

The generator records 10 spelling variants around Costello, aproper noun. Corpus frequency is #39,727 among 8,609 “C” headwords. Dominant gloss: "Nom de famille irlandais.".

Our generated misspelling index lists 10 likely wrong-spelling variants for Costello, with forms such as "ccostello", "cosetllo", and "cosstello". 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 1 confusable-pair relationship, "Castillo", a pairing that trips writers up because the two words share enough sound or shape to blur together.

This headword's origin isn't recorded in our source data, so any spelling logic here comes from how the word's sounds map to letters, not a documented origin story. The correct French form is Costello, spelled C-O-S-T-E-L-L-O.
