Frequency seat of misspelling magnet “undulating”
A misspelling magnet
The generator records 15 spelling variants around undulating, anadjective. Corpus frequency is #33,472 among 1,433 “U” headwords. Wiktionary lists 2 senses, so context still picks the gloss.
Our generated misspelling index lists 15 likely wrong-spelling variants for undulating, with forms such as "nudulating", "udnulating", and "unddulating". 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 is not paired with a close-neighbour confusable in our dataset, which tends to mean the word is visually distinctive enough to stand on its own.
No borrowing history is documented for this entry, so its spelling is easiest explained by how it's pronounced rather than where it came from. The correct English form is undulating, spelled U-N-D-U-L-A-T-I-N-G.
