This book studies four selfinitiated sameturn repair strategies in talkininteraction relative to each other namely recycling replacement insertion and aborting. Based on a thorough analysis of a Hungarian corpus as well as the previous results on another nine languages this book proposes a preference hierarchy model of repair operations that interprets sameturn repair operations relative to each other.ampnbspThis preference hierarchy model reinterprets the relationship between the principle of intersubjectivity and the principle of progressivity in talkininteraction. Saying that the principle of maintaining progressivity also has an impact on the principle of maintaining intersubjectivity not only vice versa it supposes a twoway relationship between intersubjectivity and progressivity. The speakers possible choices of repair operations relating to selfrepair depend on at least three factors the function of repair operations the number of respects in which they override the preference for progressivity and the morphosyntactic structure of the language used. This also highlights the interaction between grammar and pragmatics.ampnbspAlthough the object theoretical background of the book is conversation analysis the methodological apparatus of conversation analysis is supplied by other methods to enhance the reliability of the results. This book will provide interesting reading not only for conversation analysts but for all who are interested in talkininteraction and linguistic theorising in general.
