Ser means “to be”
There are 6 forms of ser:
Yo:Soy Nosotros/ Mis amigos y yo: Somos
Tú: Eres Vosotros (Spain only): Sois
Él/Ella/Usted: Es Ellos/Ustedes: Son
It is used in the following ways
D - description
O - origin (where you’re from)
C - characteristics
T - time and date
O - occupation
R - relationship
For example:
Exercise A
1. Jeremy and Evan son divertidos (when there is more than one person the adjective becomes plural)
7. Antonio es guapo
Exercise B
1. Alejandro es arquitecto
3. Fred y Linda son músicos (plural because there are two people)
7. Anna y yo somos enfermas
8. Tú eres banquera (switch the ending from “o” to “a” on banquera because it is feminine)
Hope this helped! I tried to do one of each form so you can get the gist. Feel free to reach out if you have any more questions
