Ser and estar both mean “to be”. Ser is used to talk about WHAT something is. This includes date, occupation, characteristics, time, origin, and relationship. Estar is used to talk about HOW something is. This includes position, location, action, condition, and emotion.
Examples of ser:
-Yo soy alta.
-Ella es inteligente.
Examples of estar:
-El está triste.
-Estoy mirando la tele.
Hopefully this helps. I put the accent marks on there too just in case you needed to write with all the correct accent marks too.
I will answer this by translating it.
I : Yo - Ar= o Er= o Ir= o
You : Tú. - = as = es = es
He/she/it : Él/Ella - = a = e = e
We : Nosotros - = amos = emos = imos
You(pl) : Vosotros - = áis = éis = Ís
They : Ellos - = an = en = en
