In Spanish the Words Ser and Estar both mean "To Be", but you cant just use ser and estar interchangeably, no, no you cant, mwahahhaha mwahahhaa...ok...now that that is over, we can move on. Ser is used for describing things more permanent such as where you are from and estar is used for more temporary such as where you live...for exampe "Yo soy aburrido" means I am a boring person, while "Yo estoy aburrido" means I am bored. What? your wondering where soy and estoy came from, soy and estoy are both conjegations of the words ser and estar. You use soy and estoy to say I am, you use eres and estas to say you are, es and esta to say he/she or you formal, somos and estamos to say we are, sois and estais to say you are in spain, and son and estan to say they, you outside of spain, and you formal in spain are. Well I think you have the basic idea of ser and estar no, so Ill be ending this blog, goodbye, and LONG LIVE THE REVOLUTION!
