HEY Mercury! "Ser" and "estar" both mean "to be." The only difference in both of them is that "ser" is permanent and "estar" is temporary. Estar is used for things that are temporary such as one's mood. Ser is used for things that are permanent such as one's nationality.

"estar" is for a places for example: voy a estar en españa is in future, and "ser" for example: el va a ser arquitecto (is in future of yo soy, el es, nosotros somos.)

I'm not a linguist, justa native spanish speaker. here some easy-digestion examples: SER: (to be, but not related to locations or conditions): Yo 'soy' chileno (I'm chilean) 'Somos' personas con ganas de aprender (We are people willing to learn) Esta respuesta no 'es' de un experto ! (This answer is not from an expert) ESTAR (to stay, to remain, places, and conditions) 'Estás' en tu casa ahora? (Are you at home now?) En general, no 'estoy' conectado mucho tiempo (Usually, I'm not online for too long) Tu 'estás' preguntando algo (you are asking something)

otra respuesta/another answer you use the verb "estar" when you are in some place. I am in Spain/ Yo estoy en España and you use this verb when you are doing anything. Example: I am writting a letter/ Yo estoy escribiendo una carta. The verb "ser" is used when you are making a description . Example I am a girl/ Yo soy una chica. I hope help you
