antefirma
title of signatory

había transcurrido un año; entre ib y cristina se habían cruzado dos cartas, con las palabras «fiel hasta la muerte» por antefirma. un día el barquero se presentó en casa de ib, trayéndole saludos de la muchacha y un encargo algo más peliagudo.
during the next year, two letters passed between ib and christina. they were signed, "faithful till death;" but at the end of that time, one day the boatman came over to see ib, with a kind greeting from christina. he had something else to say, which made him hesitate in a strange manner. at last it came out that christina, who had grown a very pretty girl, was more lucky than ever.
