ser + Profession/Nationality/Origin
Ser for Identity
Use 'ser' to talk about jobs, nationalities, and where someone is from.
How It Works
The verb ser is essential for talking about identity. One of its main jobs is to state a person's profession, nationality, or origin.
1. Professions
To say what someone does for a living, use the formula: Subject + ser + profession.
- Soy estudiante. (I am a student.)
- Mi padre es médico. (My father is a doctor.)
Articles With Professions
A plain occupational description normally omits un/una: Ella es abogada. An evaluative description often uses an article: Ella es una abogada excelente. A classifying modifier need not trigger it: Es médica forense.
Do not label every profession with un or una incorrect. Context can support emphasis or a fuller characterization, as in Es un abogado, un defensor de los derechos humanos. The useful beginner model is article-free for a neutral job description, not an absolute ban.
2. Nationalities
Use ser + nationality to say where someone is from. Nationalities are adjectives, so they must match the gender and number of the person.
- Juan es español. (Juan is Spanish.)
- María es española. (María is Spanish.)
- Ellos son españoles. (They are Spanish.)
3. Origin
To state the specific city or country someone is from, use the formula: ser + de + place.
- Yo soy de Chicago. (I am from Chicago.)
- ¿De dónde eres? (Where are you from?)
Examples (5)
- Mi hermana es ingeniera.
My sister is an engineer.
Word by Word: My sister is engineer.
- Ellos son de Colombia.
They are from Colombia.
- Tú eres francés, ¿verdad?
You are French, right?
- Soy un profesor muy paciente.
I am a very patient teacher.
Un introduces an evaluative description with muy paciente. Not every modifier requires an article: a classifying description such as Soy profesor de medicina can remain article-free.
- Nosotras somos estudiantes de medicina.
We are medical students.
Common Mistakes
Using a singular form of ser with an explicitly plural subject.
Ellos es médicos.Ellos son médicos.Match ser to ellos: son. A plain professional description normally has no article. Él es un doctor is not universally ungrammatical; its suitability depends on the intended emphasis and context.
Using 'estar' instead of 'ser' for identity
Yo estoy profesor.Yo soy profesor.Use ser directly with this profession noun: Soy profesor. The different construction Estoy de profesor describes working in that role. Do not reduce ser and estar to a permanent-versus-temporary rule.

Foundations - ser / estarSer vs. Estar Basics
Ser directly predicates professions and nationalities. This is a constructional distinction, not a claim that a job can never change; estar de can describe acting in a role.
Level 1 - un/una/unos/unasIndefinite Articles
It's important to know when not to use these articles. With professions, you usually omit them, which is a key rule related to this pattern.
Foundations - Adjective Agreement
Nationalities function as adjectives and must agree in gender and number with the person they describe (e.g., 'mexicano' vs. 'mexicana').
