In Spanish, there are two copula verbs SER and ESTAR. Ser is equivalent to the be verb in English, and estar and ser both represent state or something, but ser represents human attributes, and estar is temporary.

Ser is used to indicate a permanent situation with no signs of change.

ej:

My name is Chico.

China soybean. I come from China.

2.estar means a temporary feature or state that won't last long.

ej:

Estella Cansado. He is very tired.

Let's go on holiday. I'm on vacation.

Third, the same adjective is used with ser and estar respectively, indicating different meanings.

ej:

Esto Delgado. (I've lost weight recently)

Soybean Delgado. (I am a thin man)

Estaguapa. (She is very beautiful now)

It's Guapa. (She was born beautiful)

Estaing Wilders, Las Manzanas. (Apple is not yet ripe)

Ferdis, son of Lars Manzanas. (green apple)

Fourth, it can sometimes be distinguished in meaning. Ser has active meaning and estar has passive meaning.

ej:

Eres sorprendente。 You're amazing.

I love you. I'm surprised.

Yes, too many. He is a boring person.

Ser stands for the essence of things or people.
