La palabra del día: Endosar

Verb. Assign a bill of exchange or other credit document issued to the order in favor of someone, thus stating it signing on the back (dorso). E.g.: Para reintegrar dinero de tu cuenta puedes rellenar un módulo en la ventanilla de tu banco, endosa un cheque a “Yo mismo” o usar la tarjeta de débito: To withdraw money you can fill out a form at the bank counter, write a check to “myself” or use the Automatic Teller Machine (ATM). The noun is el endoso.
This verb can also be translated as ‘to back’ an idea, a proposal, a candidate, etc.; and it makes sense as dorso means back. From dorso we have dorsal a masculine noun and also an adjective in Spanish. dc
