A formal "excuse me" for strangers

Disculpe

dees-KOOL-peh — Excuse me (formal)

"Disculpe, ¿sabe dónde está la parada del autobús?"
Excuse me, do you know where the bus stop is?

The usted form, for strangers, older people and anyone in uniform. Its tú twin is "disculpa" — the ending changes with the register, just like perdona/perdone.

"What I say to any older lady I stop on the street for directions — the usted comes out automatically."— Graciela
