Questions & Answers about Al llegar a mi dormitorio, dejo el móvil en la mesa.
Al llegar is a common structure in Spanish: al + infinitive. Literally it’s “upon arriving” or “on arriving”.
- Al = a + el (to + the)
- llegar is the infinitive “to arrive”
So al llegar a mi dormitorio ≈ “when I arrive at my bedroom”, but with a slight nuance of “as soon as / upon arriving”, emphasizing that the action that follows happens immediately afterward.
You could also say:
- Cuando llego a mi dormitorio, dejo el móvil en la mesa.
That’s perfectly correct. Al llegar is a bit more compact and often feels slightly more formal or written than cuando llego.
