Forty or Fourty: What’s the Difference?

It’s a common complaint among people who are learning English that the language lacks consistency. English was spoken in both the Old and New Worlds at a time when rapid communication across long distances was impossible, which has led to a differing and sometimes contradictory set of conventions.

The same word can be spelled differently in American and British English, for instance. This duality can be confusing, but not every word has multiple spellings.

Many people aren’t sure whether to write the number 40 as forty or fourty. It’s a common misconception that fourty is conventional in British English, while forty is the Americanized version.
