I have to
He de haber perdido mi llave en el camino.
I must have lost my key along the way.
Lo acompañaré, yo también he de ir.
I will accompany him, I must go too.
— La Nuit américaine (1973)
I don't remember what I have to do.
Vámonos, he de tomar algo para recuperarme.
Let's go; I need to have something to recover.
— Roma città aperta (1945)
