Who to Spell 40: Understanding the Nuances of "Forty"

When it comes to writing numbers, especially those in the tens, many people find themselves pausing and questioning the correct spelling. One of the most common points of confusion revolves around the number 40. Is it "fourty" or "forty"? Let's delve into the definitive answer and explore why this particular spelling has become the standard.

The Correct Spelling of 40

The universally accepted and grammatically correct way to spell the number 40 in American English is forty.

This spelling might seem counterintuitive to some, especially if they're thinking about the word "four," which is spelled with a "u." However, the spelling of "forty" has a historical precedent and has been the standard for centuries. It's a common exception to the general rule that numbers ending in "ty" are spelled by taking the root word and adding "ty."

For instance:

• 10 is ten
• 20 is twenty
• 30 is thirty
• 50 is fifty
• 60 is sixty
• 70 is seventy
• 80 is eighty
• 90 is ninety

Notice how all these numbers, except for forty, directly relate to their base number (two for twenty, three for thirty, etc.). The spelling of "forty" deviates from this pattern.

Why the Discrepancy? A Look at Etymology

The reason for the unique spelling of "forty" lies in its linguistic roots. The word "forty" evolved from the Old English word "fēowertig," which itself is a combination of "fēower" (meaning four) and "tig" (meaning ten). Over time, the pronunciation and spelling shifted, and "fēowertig" eventually became "forty."

This historical linguistic drift led to the spelling we use today. While the connection to "four" is evident in the pronunciation, the spelling diverged.

It's important to remember that language evolves, and sometimes spellings become exceptions to general rules. "Forty" is a classic example of this.

Common Mistakes and How to Avoid Them

The most frequent error is spelling 40 as "fourty." This mistake often arises from the tendency to apply the general rule of adding "ty" to the base number "four."

To ensure you spell it correctly:

1. Memorize it: Simply commit "forty" to memory as the correct spelling for the number 40.
2. Associate with "four": While the spelling is different, remember that "forty" is the word for the number four multiplied by ten. Think of "four" and then remember the "t" instead of "u" when spelling.
3. Practice writing it: The more you write "forty" in sentences and contexts, the more natural it will become.

When to Use the Numeral vs. the Word

In American English, there are general guidelines for when to use the numeral (40) versus spelling out the number (forty):

• Spell out numbers below ten: Generally, numbers one through nine are spelled out. For example, "I have five apples."
• Use numerals for numbers ten and above: Numbers ten and above are typically written as numerals. For example, "There are 15 students in the class."
• Consistency is key: If you are using a series of numbers, maintain consistency. If you have numbers both below and above ten in a sentence or list, you might spell out the smaller ones and use numerals for the larger ones, or vice-versa depending on your style guide.
• Formal writing vs. informal writing: In very formal writing, you might see numbers spelled out more frequently. In less formal contexts, or when dealing with technical data, numerals are often preferred.
• Specific contexts: Certain contexts have specific rules. For example, in dates, we usually use numerals (e.g., July 4, 1776). Ages are often spelled out for younger children and use numerals for older individuals (e.g., "a five-year-old" vs. "she is 45").

So, when referring to the number 40, unless a specific style guide dictates otherwise, you will generally use the numeral 40 for numbers ten and above. However, when you do choose to spell it out, the correct form is always forty.

Conclusion

Understanding the correct spelling of numbers like "forty" is a small but important aspect of clear and accurate writing. While it may seem like a minor detail, using the proper spelling demonstrates attention to detail and a solid grasp of the English language. Remember, the correct spelling is forty, a testament to the fascinating evolution of words.
