A misspelling magnet

The generator records 17 spelling variants around underground (IPA [ʌn·də(r)ˈɡraʊnd]), anadjective. Corpus frequency is #25,800 among 2,159 “U” headwords. Wiktionary lists 2 senses, so context still picks the gloss.

Our generated misspelling index lists 17 likely wrong-spelling variants for underground, with forms such as "nuderground", "udnerground", and "undderground". 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, "Untergrund", a pairing that trips writers up because the two words share enough sound or shape to blur together.

This entry's etymology isn't recorded, so its spelling is easiest explained by how it's pronounced rather than where it came from. The correct German form is underground, spelled U-N-D-E-R-G-R-O-U-N-D.
