The division of labour between the Basque articles in the indefinite domain

The usage of the Basque definite and indefinite articles differs significantly from their Romance counterparts. While the definite article is used as a default article for NPs without another determiner, the exact function of the indefinite article in this system has remained somewhat unclear, although specificity has been brought up as a factor. A comparison with Eastern Armenian, which has a threefold definiteness/specificity distinction, in three parallel texts shows that the use of the indefinite article in Basque follows two different systems in different varieties: in the West it is based on discourse prominence and in the East on individuation.
