Quick Ans: Fourty or forty? The correct spelling is “forty.” “Fourty” is a common spelling mistake. Although the word comes from “four,” it drops the “u” when written as “forty.” Use “forty” when writing the number 40 in English, whether you’re writing a sentence, date, age, price, or measurement.
Are you confused about whether to write “fourty or forty”? You’re not alone. This is one of those English spelling mistakes that seems logical because the number 4 is spelled “four.”
However, the number 40 does not follow the same pattern. Its correct spelling is “forty,” without the letter “u.”
For example, you should write, “She is forty years old,” not “She is fourty years old.” The same rule applies whether you’re writing casually, professionally, or academically.
The mistake usually happens because people naturally connect “forty” with “four.” That makes “fourty” look reasonable. English spelling, though, doesn’t always follow simple patterns.
Once you remember that “forty” drops the “u,” the difference becomes easy. You can use the correct spelling confidently in emails, schoolwork, articles, forms, and everyday writing.
