Our generated misspelling index lists 14 likely wrong-spelling variants for unilateral, with forms such as "nuilateral", "uinlateral", and "unialteral". Each of these forms differs from the correct spelling by one small edit: a doubled letter, a dropped silent letter, or a substituted vowel. It also participates in 1 confusable-pair relationship, "unilaterally", a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: A modern creation (circa 1802), from New Latin ūnilaterālis (“one-sided”), from Latin ūnus (“one”) + laterālis (“sided, lateral”), equivalent to uni- + lateral. The correct English form is unilateral, spelled U-N-I-L-A-T-E-R-A-L.
