This article analyses the semantic features of two constructions characterised by the specific use of morphosyntactic indicators of the category of number. The constructions are based on unusual, unobvious ways of using singular and plural forms of NP. The singular (in the first construction) and plural (in the second) forms of NP give to the constructions a metonymic character. The constructions are described as two types of metonymy, representing two different ways of construal.
