Cancelable vs. Cancellable
“Cancelable” and “cancellable” are both documented spellings. Cambridge marks “cancelable” as the usual U.S. form and “cancellable” as the British form, while noting U.S. preference for “cancelable.”
Both are correct regional variants: U.S. English usually prefers “cancelable,” while British English uses “cancellable.”

Caveat: Both forms are standard regional variants; do not label the other form a grammar error.
