A misspelling magnet

The generator records 8 spelling variants around linear (IPA /ˈlɪni.ə/), anadjective. Corpus frequency is #5,894 among 2,297 “L” headwords. Wiktionary lists 10 senses, so context still picks the gloss.

Our generated misspelling index lists 8 likely wrong-spelling variants for linear, with forms such as "ilnear", "lienar", and "linaer". 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, "lines", "liver", "lined", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: Borrowed from Latin līneāris, from līnea (“line”) + -āris (adjectival suffix), equivalent to line + -ar. Doublet of lineal. The correct English form is linear, spelled L-I-N-E-A-R.
