Mold or Mould: What is the Difference?

Mold vs Mould?  Which one is correct?

Well, whether you would spell it mold or mould really depends on where you live.

Americans spell it as mold while the British add the letter ‘u’ after the ‘o’, spelling it mould. Ultimately, both versions mean the exact same thing.

Similarly, the word color is another good example. The British spell it as colour whereas the Americans remove the ‘u’, spelling it as color. However, in the end, the meaning is equal.

Canadians and Australians most often favor the British spelling (mould).  However, ‘mold’ is commonly found in Canadian literature because of the shared border with the United States.
