Mistake 2: Mixing Spelling Styles
A document can become inconsistent if it uses both American and British spelling without a reason.
For example:
- The company will fulfil the order.

Think of the regional spelling like this:
US English → fulfill → two Ls at the end
UK English → fulfil → one L at the end
A simple reminder is:

Remember that the past and -ing forms use double l in both varieties:
- fulfill → fulfilled → fulfilling
- fulfil → fulfilled → fulfilling
American vs British English

Other English-speaking regions may follow British or American conventions, or have their own established preferences. Australian and New Zealand English, for example, commonly follow British spelling conventions in many contexts.
