The Origin of Labeller or Labeler

The word label comes from the Old French word labelle, meaning a small tag or ribbon. It entered English in the Middle Ages.

When English spread across different regions, spelling rules evolved differently.

British English tends to double the final “l” when adding endings like -er or -ing.

American English simplified many spellings in the 19th century, largely influenced by lexicographer Noah Webster. That’s why spelling differences like labeller vs labeler still exist today.
