What Does Forty Mean?
The most common meaning of forty is simply the written form of the number 40.
However, in slang and cultural conversations, “forty” can also refer to a 40-ounce bottle of malt liquor, particularly in American street culture, hip-hop lyrics, and older urban slang.
Quick Answer
Forty meaning usually refers to the number 40. In slang, it may also describe a 40-ounce bottle of malt liquor. The intended meaning depends entirely on the context.
Origin of the Word
The word “forty” comes from Old English numerical language and has existed for centuries as the standard spelling of the number 40.
The slang version emerged much later. During the late 20th century, the term became associated with large 40-ounce beverage bottles that were popular in parts of the United States. Music, movies, and pop culture helped spread this alternative meaning.
How the Meaning Has Evolved
Originally, forty had only one meaning: the number itself.
Over time, cultural references expanded its usage. Today, people may use it when discussing:
- Age milestones
- Historical events
- Quantities
- Sports statistics
- Alcohol-related slang
- Social media jokes and memes
Pronunciation Guide
Forty is pronounced:
FOR-tee
Phonetic spelling:
/ˈfɔːr.ti/
Fourty or Forty
If you have ever typed “fourty” and wondered whether your spelling looks right, you are not alone. The correct spelling is “forty” without the u. While “four” is spelled with a u, the number 40 takes a slightly different spelling: forty.
Fourty is a common misspelling of forty, not an accepted standard spelling in modern English. The correct form is used everywhere, including formal writing, schoolwork, business communication, and everyday conversation.
Here are a few quick examples:
- Correct: She is forty years old.
- Incorrect: She is fourty years old.
- Correct: He scored forty points.
- Incorrect: He scored fourty points.
Why is it “forty” instead of “fourty”?
The spelling comes from the historical development of the English number word. Although forty is related to four, English spelling does not always preserve the exact form of the root word. Over time, the spelling settled on forty, and that is the standard form used today.
Easy trick: Think of four + ty → forty, but drop the u. If you are writing the number 40, remember: forty is correct; fourty is not.

Forty Meaning in Tennis
In tennis, forty is a scoring term that represents the third point won by a player in a standard game.
Tennis scoring can seem strange at first because points traditionally progress as:
Love → 15 → 30 → 40 → Game
So, if a player has won three points while their opponent has won one, the score is 40–15. If both players have won three points, the score is 40–40, which is called deuce.
For example:
The interesting part is that 40 does not simply mean the player has scored forty points. It is a traditional scoring label.
What does 40–40 mean?
When both players reach 40, the score becomes deuce. From deuce, a player generally needs to win two consecutive points to take the game:
Deuce → Advantage → Game
So if you hear a commentator say, “It’s forty-all,” they mean the players are at 40–40, or deuce.
Why does tennis use 15, 30, and 40?
The exact historical origin of tennis scoring is debated, but the familiar 15–30–40 system has been used for centuries. One popular explanation connects the numbers with an old clock-face scoring system, although historians do not consider that explanation definitively proven.
What matters for modern players is simple: forty is the third scoring stage in a standard tennis game, immediately before game point.
Forty Meaning Slang
As slang, forty can mean different things depending on the conversation and cultural context. Unlike its standard dictionary meaning as the number 40, slang uses are often shaped by music, sports, regional speech, and online communication.
One well-known slang use of forty or a forty refers to a 40-ounce bottle of beer or malt liquor, particularly in American informal speech. For example, someone might say, “He picked up a forty,” meaning a large 40-ounce alcoholic drink.
The word can also appear in hip-hop and street slang, where “forty” may refer to a .40-caliber firearm. In that context, the meaning comes from the caliber rather than the number itself.
Because slang depends heavily on context, you should not automatically assume that every use of forty has the same meaning.
Examples of “forty” in slang
- “He grabbed a forty.” → Could refer to a 40-ounce alcoholic drink.
- “He was talking about a forty.” → In some contexts, this may refer to a .40-caliber firearm.
- “I’m turning forty.” → This is not slang; it simply means reaching the age of 40.
So, when you encounter forty in a text, song, social media post, or conversation, look at the surrounding words before deciding what the speaker means. The same number can have a completely different meaning in everyday English, sports, or slang.
