There are two types of disjunction: exclusive and inclusive (Levinson, 1983: 138). If it is exclusive, it forces a choice on the part of the hearer between the alternatives. In kahve veya çay ikram edebilirim, the speaker does not expect the hearer to have them both. In evde yoklar veya duymadılar, there is no such exclusive interpretation. Both alternatives are possible, so it is an example of inclusive disjunction. Double coordination is not a allowed in Turkish: *Ne Ayşe’yi tanıyorlar ama ne de biliyorlar.
