A misspelling magnet

The generator records 6 spelling variants around assume (IPA /əˈsjuːm/), averb. Corpus frequency is #2,611 among 3,931 “A” headwords. Wiktionary lists 5 senses, so context still picks the gloss.

Our generated misspelling index lists 6 likely wrong-spelling variants for assume, with forms such as "assmue", "assuem", and "assumme". 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 6 confusable-pair relationships, "assure", "astute", "assumed", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.

Etymologically, the entry records: From Latin assūmō (“accept, take”), from ad- (“to, towards, at”) + sūmō (“take up, assume”). The correct English form is assume, spelled A-S-S-U-M-E.
