A label can provide information such as:
- A product name

The noun comes from the verb label.

The Main Difference Between Labeller and Labeler
The main difference is spelling style, not meaning.
Labeler
Labeler is the spelling commonly used in American English.
Example:
The company bought a new automatic labeler.
Labeller
Labeller is the spelling commonly used in British English.
Example:
The company bought a new automatic labeller.
Both sentences have the same meaning.
The only visible difference is the extra l in labeller.
Why Does Labeller Have Two Ls?
The difference comes from how American and British English handle the final l when adding the suffix -er.
The base word is:
label
Adding -er can produce two standard forms:
American English:
label + er = labeler
British English:
label + ler = labeller
British English often doubles the final l in words of this type, while American English commonly keeps a single l.
This is why you may also see differences such as:
| American English | British English |
| Labeler | Labeller |
| Traveler | Traveller |
| Canceled | Cancelled |
| Labeled | Labelled |
These patterns can vary from word to word, so they should not be treated as a rule that applies to every English word.

The word label entered English through Old French and has historical connections with a strip, ticket, or piece of material attached to something.
Over time, its meaning expanded to include a piece of information attached to a product, object, or document.
When -er is added to label, it creates a noun for a person or thing that performs the action:

- label + ler = labeller
The two forms developed as part of different English spelling conventions.
