I’m back with another progress update! Sticking with self-studying Spanish isn’t easy, but I’ve recently tackled one of the toughest nuts to crack: Ser and Estar! I’m sure many of you, like me, were completely confused when you first encountered these two ‘to be’ verbs. Today, I want to share how I distinguish and remember them, hoping to help anyone who’s still struggling.
Ser: Permanence and Essence
The first rule of thumb I came up with is: Ser is for things that are ‘nailed down’ and don’t easily change. It describes the essence, identity, nationality, profession, time, and ownership of something—attributes that are relatively stable and objective. For example, ‘I am a student’ defines my identity, which isn’t going to change in the short term, so you use Ser.
- Nationality: Soy de China.
- Profession: Mi padre es médico.
- Personality: Ella es muy simpática.
- Time: Son las tres de la tarde.
Simply put, if you feel a description defines the core of ‘what’ something is, you can’t go wrong with Ser.
Estar: State and Location
Estar, on the other hand, is much more flexible. My rule of thumb is: Estar is for ‘temporary’ things that can change at any moment. It’s mainly used to describe someone’s emotions, health, location, and other temporary conditions, which is a common hurdle when self-studying Spanish. For example, I’m in a good mood now, but that might change in a moment. This is a temporary state, so you have to use Estar.

- Location: Estoy en casa.
- Emotion: ¿Por qué estás triste?
- Condition: La sopa está caliente.
- Health: Mi abuela está enferma.
Remember, whenever it involves a location or a state that could change at any moment—a frequent occurrence when you learn Spanish on your own—it’s a no-brainer to use Estar.
A Little Practice to Tell Them Apart
To reinforce what we’ve learned, I’ve put together a small table. You can see how these two verbs can completely change the meaning of the same adjective in different contexts. This is one of the most interesting and confusing parts of learning Spanish from scratch!
| Adjective | With Ser | With Estar |
| listo | Ser listo | Estar listo |
| bueno | Ser bueno | Estar bueno |
| aburrido | Ser aburrido | Estar aburrido |
| rico | Ser rico | Estar rico |
So, is it much clearer now? Especially the last one, rico—be careful not to use it wrong when you’re out eating with friends, or it could get awkward, haha. The self-study journey is full of pitfalls, but mastering each new concept is incredibly rewarding! Do you have any other good memory tips? Feel free to share and discuss in the comments below.
