The spelling of numbers has caused confusion for many people and always will because there are a few issues with some numbers when they’re in written form—like the number 40. Is it forty or fourty? I’ll explain why it’s spelled the way it is, plus show you how to write it in a sentence.
Is It Fourty or Forty? The Spelling of 40 Unveiled
So, even though the number four is spelled with a “u,” the correct spelling you should use for 40 is, in fact, “forty”—no “u” in sight. “Fourty” isn’t an alternative spelling. Sure, it might seem counterintuitive initially, but this spelling is the one you’ll find in dictionaries and the best grammar guides, making it the widely accepted and standardized form in English-speaking countries.
Why Is 40 Spelled Forty and Not Fourty?
The simple reason behind the spelling of 40 as forty and not fourty comes from the history of the English language. Old English, which is what Modern English is derived, used the word “feowertig” to represent the written number 40. Then the language just evolved over time, and the pronunciation and spelling obviously changed. The “u” was eventually dropped in favor of the more modern and streamlined “forty.”
Is It Forty-One or Fourty One? And How to Use the Hyphen
Listen up. This rule applies to all compound numbers. When you write the numerical word for 40, it’s “forty,” but when it comes to the next nine numbers after it, you need to hyphenate them. So, it’s forty-one, forty-two, forty-three, forty-four, and so on.
Side note, you’d also use a hyphen when using the word “forty” in conjunction with a noun as an adjective, like “forty-year high” or “forty-year-old.”
