Quick Ans: Labelled and labeled are both correct spellings of the past tense and past participle of label. Labeled is commonly used in American English, while labelled is preferred in British English and other varieties. Both words have the same meaning, so the correct choice depends mainly on the spelling style you follow.
Labelled or labeled is a common spelling question because English uses different spelling conventions in different regions. Both forms come from the verb label, which means to attach a name, description, or identifying mark to something.
The main difference is simple. Labeled has one l before the ending, while labelled has two. American English generally uses labeled, whereas British English commonly uses labelled.
You may see both spellings in books, websites, academic papers, product packaging, and workplace documents. Neither spelling changes the meaning of the word.
Knowing the difference can help you avoid unnecessary spelling mistakes and keep your writing consistent. Once you learn the regional rule, choosing between labelled and labeled becomes much easier.
