A misspelling magnet

The generator records 14 spelling variants around secondary (IPA /ˈsɛkənd(ə)ɹɪ/), anadjective. Corpus frequency is #2,861 among 6,566 “S” headwords. Wiktionary lists 12 senses, so context still picks the gloss.

Our generated misspelling index lists 14 likely wrong-spelling variants for secondary, with forms such as "escondary", "sceondary", and "seccondary". 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, "secondly", a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: From Middle English secundarie, from Latin secundārius (“of the second class or quality”), from secundus (whence the English second) + -ārius (whence the English suffix -ary), equivalent to second + -ary; compare the French secondaire, the Italian secondari… The correct English form is secondary, spelled S-E-C-O-N-D-A-R-Y.
