Our generated misspelling index lists 7 likely wrong-spelling variants for Jason, with forms such as "ajson", "jaosn", and "jasno". 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 18 confusable-pair relationships, "Jon", "JSON", "jeon", and more, where similar look or sound leads writers to substitute one word for another in context.
