💡 Quick Rule
Clase = the lesson or the students. Aula = the physical room.
Think: 'Clase' is the class you take. 'Aula' is the hall you take it in.
- Informally, people might say '¿En qué clase estás?' to ask 'Which classroom are you in?', but 'aula' is more precise.
- 'Dar clase' (to teach a class) is the action that happens inside an 'aula' (classroom).

Voy a clase.
I'm going to class. (The event/lesson)

La clase de química es mi favorita.
Chemistry class is my favorite. (The subject)
With "aula":
El aula de química tiene ventanas grandes.
The chemistry classroom has big windows. (The room)

⚠️ Common Mistakes
El aula de historia fue difícil.
La clase de historia fue difícil.
The subject matter was difficult, not the physical room. Use 'clase' to talk about the content of the lesson.
Nos vemos en la clase 204.
Nos vemos en el aula 204.
When referring to a specific, numbered room, 'aula' is the correct and more precise term.
La aula es grande.
El aula es grande.
This is a grammar trap! 'Aula' is a feminine noun, but it uses the masculine article 'el' in the singular to avoid the awkward 'a-a' sound.

Frequently Asked Questions
I've heard 'salón de clase'. How is that different?
'Salón de clase' or just 'salón' is a very common synonym for 'aula', especially in Latin America. Functionally, 'aula' and 'salón' both mean the physical classroom. 'Clase' still refers to the lesson or students.
Why is it 'el aula' if 'aula' is a feminine word?
It's a rule in Spanish to prevent two stressed 'a' sounds from running together. Feminine nouns that start with a stressed 'a' or 'ha' sound (like agua, hacha, águila) use the masculine article 'el' in the singular. But they are still feminine, so any adjectives must be feminine (el aula bonita) and the plural form is normal (las aulas bonitas).
