A misspelling magnet

The generator records 5 spelling variants around loco (IPA [ˈloko]), anadjective. Corpus frequency is #972 among 2,069 “L” headwords. Wiktionary lists 10 senses, so context still picks the gloss.

Our generated misspelling index lists 5 likely wrong-spelling variants for loco, with forms such as "lcoo", "lloco", and "locco". 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, "los", "low", "Lou", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.

No documented word history exists for this headword, so spelling patterns must be inferred from the word's phoneme-to-grapheme mapping rather than from a documented borrowing chain. The correct Spanish form is loco, spelled L-O-C-O.
