📚 Las formas — SER and ESTAR at a glance

Before you can choose between ser and estar, you need the forms locked in memory. Both verbs are irregular in the present tense — there is no shortcut. Learn these six forms for each verb, and every rule that follows becomes usable.
Pronombre SER (to be — permanent) ESTAR (to be — temporary)
yo soy estoy
eres estás
él / ella / usted es está
nosotros/as somos estamos
ellos / ellas / ustedes son están

Two verbs, one English word — choosing wrong is the most penalised grammar error at GCSE.

⚠️ Los errores más frecuentes — the two errors that cost most marks

These two mistakes appear repeatedly in GCSE writing and speaking. Both involve ser contexts that learners incorrectly replace with estar.

❌ Error 1 (Profesión): Estoy médico.

✅ Correcto: Soy médico.

Por qué: Profession is a defining characteristic, not a temporary state — it uses ser. The form estoy + profession does not exist in Spanish and will be penalised immediately by an AQA examiner.

❌ Error 2 (Ubicación de un evento): La reunión está en el aula.

✅ Correcto: La reunión es en el aula.

Por qué: The location of an event (meeting, class, concert, wedding, conference) uses ser — not estar. This is the most common advanced ser/estar error. Compare: El aula está en el edificio A. — here the classroom (a permanent physical object) uses estar for its location. Events → ser; objects and people → estar.
