Cómo funcionan los apellidos en España

What does “rellenar” mean in Spanish?

On her first day at work, Gloria has to fill in her ID card — “tiene que rellenar su tarjeta de identificación.” In Spain, “rellenar” is the normal word for completing a form: you write your details into the blank spaces. The clip even names them — “casillas,” the little boxes for your first name and your two surnames. So when paperwork says “rellenar,” it just means write your information in the blanks.

Spoken line: “Gloria… tiene que rellenar su tarjeta de identificación.” = “Gloria has to fill in her ID card.” “Rellenar” is the everyday word for filling in a form or document. A few common uses: - “Rellena este formulario, por favor.” = “Fill in this form, please.” - “Tienes que rellenar todas las casillas.” = “You have to fill in all the boxes.” - “Olvidé rellenar mi nombre.” = “I forgot to fill in my name.” Good to know: outside paperwork, “rellenar” can also mean to refill or top up (a glass, a tank) — but with forms and boxes it always means write your details in the blank spaces. “Casilla” (a box on a form) is the matching word you also hear in this clip.
