“Labeller” and “labeler” mean the same thing, but the spelling depends on the type of English being used. “Labeler” is the preferred spelling in American English, while “labeller” is commonly used in British English and other regions that follow British spelling rules.
Many English words have different spellings depending on where you live. One common example is labeller or labeler. Both words look similar. Both mean the same thing. Yet many writers, students, and professionals get confused about which version is correct.
