Unlabelled vs. Unlabeled: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on November 7, 2023
"Unlabelled" and "unlabeled" mean the same—without a label—but differ in British (unlabelled) and American (unlabeled) English spelling.

Key Differences

Unlabelled, typically British English spelling, refers to items without a label or identification tag. Unlabeled, the American English variant, holds the same meaning. Both spellings are correct within their respective linguistic contexts and carry no difference in use or connotation. The choice between unlabelled and unlabeled is simply a matter of regional spelling preference.
In the context of merchandise, an unlabelled product lacks branding or a descriptive tag. Similarly, an unlabeled product in the United States would not display a brand or description. This absence of labeling can be intentional or due to oversight, and the implications are identical regardless of the spelling used.
When discussing scientific research, unlabelled samples are those not marked with identifiers. The term unlabeled is used in American journals for the same purpose. This can be critical in blind studies where the lack of labels prevents bias, ensuring the reliability of the research irrespective of the spelling.
In technology and data management, unlabelled data lacks tags or markers that identify its content or function. Unlabeled data in American English is referred to in the same way and presents the same challenges for algorithms that rely on labels for processing.
Both unlabelled and unlabeled can also describe a social context where an individual or group does not have a defining label or category. Whether one uses unlabelled or unlabeled in writing or conversation depends on the audience's familiarity with British or American English standards.
