Where “unsuitable” sits in English frequency
A misspelling magnet
The generator records 15 spelling variants around unsuitable (IPA /ʌnˈsuːtəbəl/), anadjective. Corpus frequency is #20,533 among 1,433 “U” headwords. Dominant gloss: "Not suitable.".
Our generated misspelling index lists 15 likely wrong-spelling variants for unsuitable, with forms such as "nusuitable", "unnsuitable", and "unsiutable". 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, "unstable", a pairing that trips writers up because the two words share enough sound or shape to blur together.
Etymologically, the entry records: From un- + suitable. The correct English form is unsuitable, spelled U-N-S-U-I-T-A-B-L-E.
