Quelques notes sur les déterminants nominaux един et un en bulgare et en roumain

The article aims to show some parallels and differences in the use of един and un, as determiners in Bulgarian and Romanian. Their typical function within the NP in the two languages, viz to express specific indefiniteness, and the existence of a zero determiner as a marker of nonspecific indefiniteness are pointed out. An attempt is made to determine the role of един and un in the determiner systems of the two languages.
