¡Hola! Ready to learn a cool Spanish secret? In English, we use 'to be' for everything, but Spanish has two different words for it!
In Spanish, both 'ser' (SEHR) and 'estar' (ehs-TAHR) mean 'to be'. We use 'ser' for permanent things like who you are. We use 'estar' for temporary things like where you are right now.

Think of 'ser' as your identity card. Use it for your name, your job, or what you look like. For example, 'Yo soy inteligente' (I am smart) uses 'ser' because being smart is part of who you are.
Think of 'estar' as a map or a mood ring. Use it for locations and feelings. For example, 'Yo estoy feliz' (I am happy) uses 'estar' because your mood can change in a minute!
Figure out which verb to use for this sentence: 'I am in the classroom.' In Spanish, 'the classroom' is 'el salón de clases'. Should we use 'soy' (from ser) or 'estoy' (from estar)?
- Step 1: Look at what the sentence is talking about. It says 'I am in the classroom.' This is a physical location.
- Step 2: Ask yourself: Is a location a permanent identity, or is it where you are right now? It is where you are right now. You will leave the classroom later!
- Step 3: Match it to the correct rule. We use 'estar' for locations (where you are).
- Step 4: Choose the correct form of the verb. The 'I' form of 'estar' is 'estoy'.
- Step 5: Write the final sentence: 'Yo estoy en el salón de clases' (I am in the classroom).
