In this dissertation, I investigate word order and information structure in the light of recent developments within the minimalist program. I specifically pursue a principled explanation of word order within the biolinguistic perspective. In that sense, I entertain the thesis that all properties of the faculty of language contribute to a computationally efficient satisfaction of interface conditions. The language examined is Romeyka, the only Asia Minor Greek variety still spoken in the area historically known as Asia Minor (present-day Anatolia, Turkey). The objective of this study is therefore twofold: (a) descriptively, to examine word order variation in Romeyka and (b) theoretically, to investigate whether such word order variation coul...
