If you've ever traveled to Mexico, watched a Mexican TV show, or chatted with native speakers, you've probably heard someone suddenly yell:
"¡Aguas!"
At first, it sounds confusing.
Why are they shouting "Water!" when there isn't any water around?
The answer is actually a fascinating piece of Mexican history.
What Does "¡Aguas!" Mean?
Today, ¡Aguas! simply means:
- Watch out!
- Be careful!
- Look out!
It's one of the quickest ways to warn someone about danger.
Examples
¡Aguas con el coche!
Watch out for the car!
¡Aguas con el perro!
Watch out for the dog!
¡Aguas!
Look out!
It's short, natural, and you'll hear it everywhere in Mexico.
Why Do Mexicans Say "¡Aguas!"?
The most popular explanation goes back hundreds of years.
Before modern plumbing, people often dumped dirty water from second-story windows into the street below.
To avoid soaking pedestrians, they'd yell:
"¡Aguas!"
(Water!)
That warning gave people just enough time to move out of the way.
Over time, the word stopped referring only to water and became a general warning meaning:
"Look out!"
"Be careful!"
Today, there probably isn't a bucket of dirty water coming your way—but the expression lives on.
Note: This origin story is the traditional explanation you'll hear throughout Mexico. While historians debate whether it's the exact historical origin, it's by far the most widely known cultural explanation.
When Should You Use "¡Aguas!"?
Mexicans use it whenever someone needs a quick warning.
A car is coming.
¡Aguas con el coche!
Someone almost bumps into a pole.
¡Aguas!
Your friend is about to step in a puddle.
¡Aguas!
A dog looks aggressive.
¡Aguas con ese perro!
"¡Aguas!" vs. "Ten cuidado"
Both expressions mean you should be careful, but they aren't used the same way.
Ten cuidado
Means:
Be careful.
It's more general advice.
Ten cuidado cuando manejes.
Be careful when you drive.
¡Aguas!
Is an immediate warning.
Someone is about to make a mistake.
Something dangerous is happening right now.
It's much closer to saying:
Watch out!
Look out!
Is "¡Aguas!" Only Used in Mexico?
It's strongly associated with Mexican Spanish.
Some neighboring countries understand it, but if you hear someone yell "¡Aguas!", there's a very good chance they're from Mexico or have spent time around Mexican Spanish.
It's one of those expressions that immediately sounds authentically Mexican.
Pronunciation
¡Aguas!
IPA: /ˈa.ɣwas/
Sounds like:
AH-gwas
Don't pronounce the "g" too hard.
