Questions & Answers about Mi novio es vegetariano.

Why is it es and not está?

Use ser (here, es) for identities, categories, and defining traits. Being vegetarian is treated as a classification, so Mi novio es vegetariano is correct. Mi novio está vegetariano sounds wrong. For temporary situations, use estar: Mi novio está a dieta or está comiendo menos carne.

Why is there no un before vegetariano?

After ser, Spanish typically omits the indefinite article with professions, religions, ideologies, and similar labels: es vegetariano. You can add un if you treat it as a countable noun or you add a qualifier: Es un vegetariano estricto/convencido. Both Es vegetariano estricto and Es un vegetariano estricto are heard.

How would this change if my partner is female?

Make the nouns and adjectives feminine:

• Mi novia es vegetariana.
• Plural: Mis novios son vegetarianos, Mis novias son vegetarianas.

Is there a gender‑neutral way to say this?
