This book deals with the study of how Greek grammar and syntax make possible the occurrence of overlaps in specific locations, in everyday Greek conversation. Greek grammar and syntax have specific functions (such as freer word order, much information included in the verb, subject omission) which allow interaction to occur in specific forms (displays early projectability and early occurrence of overlaps). The co-existence of the above grammatical and syntactical characteristics within a Greek turn, make possible the appearance of overlaps in specific locations. Consequently, syntactic practices of Modern Greek language shape the organisation of overlaps that occur in everyday Greek conversations. In Greek, grammar and interaction organise each other and more specifically syntactic practices of language shape the organization of overlaps. This book proposes that if over time the suggestions of this study are generalisable then it could be supported that social and national stereotypes (for example that Greeks are loud or impolite or that they talk all together and interrupt each other) actually born in interaction.
