Most of the time, the meaning stays the same, but the way the words are written can change. In this blog post, you will learn simple spelling rules to help you understand and use both styles correctly.

Why Is There a Spelling Difference?

The difference happened because English changed over time in the USA and the UK. Some changes were made to make words simpler in the USA. British English kept the old style.
