Currently, the analysis of coordination widely used within the Principles and Parameters-theory is to label them as conjunctive phrases (ConjP) with the conjunction at its head, the first element of the conjunction as the specifier, and the second element as its complement, as proposed by Munn (1978). In this thesis I plan to closely analyze this construction through established theories, previous studies and evidence found in English as well as several other languages when appropriate for the discussion. This thesis will focus exclusively on coordination of Determiner Phrases in order to establish an accessible basis for arguments for and objections against ConjP, as well as to easily foreground arguments dealing with case and agreement. From the compiled arguments I will present a judgement about the integrity of Munn’s structure. Therefore the purpose of this thesis is to find out whether coordinative phrases propose a significant problem to X’-theory, as is assumed in papers such as Borsley (2015).Show less
