Even in languages with a well-developed system of articles, such as Germanic and Romance languages, we find constructions in which the noun can appear without an article. Such constructions are often related to pseudo incorporation (cf.

Bare nouns are sometimes in complementary distribution with the indefinite article (in predication, incorporation, with/without PPs), and sometimes with the definite article (in (the) hospital, play (the) piano).
