Cuidado (interjection)
Used as a warning meaning “be careful” or “watch out”. It is not a verb here, so it does not need a subject.
con (preposition)
Introduces the thing to be careful about; translates to “with” or “about”.
el hueco (noun)
Literally “the hole” or “gap”. In everyday speech it can refer to a pothole, a missing step, or any opening that could cause a fall.
al = a + el (contraction)

✕Common Mistakes
Cuidado del hueco al subir.
“Cuidado del hueco” is incorrect because the warning uses the preposition “con” (with/about), not “de”.
Cuidado con el hueco subiendo.
Using the gerund “subiendo” changes the meaning to “while going up” and sounds less natural in this warning structure.
Cuidado con los huecos al subir.
If you refer to a single specific hole, keep it singular. Plural “huecos” would imply multiple gaps, which may confuse the listener.
↔Alternatives
Ten cuidado con el agujero al subir.
Be careful with the hole when you go up.
Mira el hueco cuando subas.
Look at the hole when you climb.
No te caigas por el hueco al subir.
Don’t fall into the hole while going up.
Cultural Tip
In many Spanish‑speaking countries, safety warnings are often delivered with a short interjection like “¡Cuidado!” rather than a full sentence. The word “hueco” is versatile; in Spain it can also mean a pothole in the road, while in Latin America it may refer to any gap or missing step. Adjust the tone: a friendly “cuidado” works with peers, but in a formal setting you might say “Por favor, tenga cuidado con el hueco al subir.”
