A misspelling magnet

The generator records 6 spelling variants around plan (IPA /plæn/), anoun. Corpus frequency is #516 among 4,417 “P” headwords. Wiktionary lists 5 senses, so context still picks the gloss.

Our generated misspelling index lists 6 likely wrong-spelling variants for plan, with forms such as "lpan", "paln", and "plann". 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 20 confusable-pair relationships, "PLC", "pun", "PSA", and more, where similar look or sound leads writers to substitute one word for another in context.

Etymologically, the entry records: Borrowed from French plan (“flat surface, ground plot, map”), from Latin plānus. Some sources also argue for influence or alteration of French plant, from plantar, from Latin plantāre (“set, fix in place”). Compare plane, plain. The correct English form is plan, spelled P-L-A-N.
