Our generated misspelling index lists 13 likely wrong-spelling variants for annotation, with forms such as "annoattion", "annotaiton", and "annotasion". Each variant is a distinct typo pattern an edit-distance generator flags, typically a doubled-consonant error, a silent-letter drop, or a vowel substitution. It also participates in 1 confusable-pair relationship, "annexation", a pairing that trips writers up because the two words share enough sound or shape to blur together.
