Section 18.1 dealt mainly with binominal constructions in which the two nouns may or must be adjacent. This section deals with binominal constructions containing a preposition. Section 18.2.1 begins with a discussion of N-van-een-N constructions such as een schat van een kata treasure of a cat, which obligatorily contain the preposition van and are used to express e.g. a metaphorical comparison: “a cat like a treasure”. This is followed in Section 18.2.2 by a discussion of the interrogative construction wat voor een Nwhat kind of N, which obligatorily contains the preposition voor and in which the interrogative pronoun wat is used to request a further specification of the set denoted by the second noun. A related construction with QBCs are so-called partitive constructions of the type vier/een aantal van die koekjesfour/a number of the cookies; this construction will not be discussed here, but in Section 20.4.
