Our generated misspelling index lists 4 likely wrong-spelling variants for auto, with forms such as "atuo", "auot", and "autto". 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, "aux", "at", "AU", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: From Ancient Greek αὐτός (autós, “self”), metanalyzed from auto- in words such as automatic, autopilot, and automobile. The correct English form is auto, spelled A-U-T-O.
