How to use it
Rellenar (un formulario) means 'to fill in / complete a form' — the standard Peninsular Spanish verb for this bureaucratic action. The more formal synonym is cumplimentar, found in official instructions. The noun is el formulario (the form/document). Latin American Spanish sometimes uses llenar in place of rellenar. Rellenar requires a direct object — you cannot rellenar without specifying the document.
Common mistake
In Peninsular Spanish, rellenar (not llenar) is the standard colloquial and formal verb for forms. Cumplimentar is the most formal register (official government instructions). Never use 'completar' alone as a standalone form-filling verb in Spanish bureaucracy — use rellenar or cumplimentar.
