ABSTRACT Commercial courses, among the most challenging and fastest-growing phenomena in language curriculum, have evolved from the realization of American business that to gain foreign markets one must be knowledgeable of foreign languages and foreign cultures. This article describes several successful activities implemented in a six-credit undergraduate commercial Spanish course at Marywood College. Supplementary materials were developed to provide linkage between practical exercises and simulations in order to improve acquisition of commercial terminology and practices. Examples from a carpeta, a file of original student correspondence, are included and the establishment of a faculty-monitored translation clinic is addressed.
