The Spanish verb SER means to be and is used to describe permanent or essential characteristics, such as identity, origin, profession, and time (Soy estudiante - I am a student, Ella es de México - She is from Mexico).
Unlike estar (which also means "to be"), ser is used for traits that don’t easily change. It’s an irregular verb with unique forms like soy, eres, es, somos, son. It's also used for telling the time (Son las tres - It’s three o’clock) and expressing relationships.| Yo | Soy |
| Tu | Eres |
| El/Ella/Usted | Es |
| Nosotros(as) | Somos |
| Vosotros(as) | Sois |
| Ellos(as)/Ustedes | Son |
| Yo soy un programador | I'm a programmer |
| Ella es una escritora technica | She's a technical writer |
| Dariia y Dmytro son Ucrañianas | Dariia and Dmytro are Ukranians |
