Yes, both SER and ESTAR mean “to be” (am, is, and are) But they are not interchangeable!!!! So, how do we know when to use each one???
someone is feeling 1. To describe how someone is feeling (temporary characteristics) such as tired, sick, sad, happy, etc. location 2.To describe location such as beside, to the left of, in, etc.
1. Whenever you don’t use “ESTAR” (and you want to say “am, is, or are”)
How you feel and where you are, this is when you use estar
Twinkle twinkle verb estar How you feel, where you are.
