Valency Alternation in Turkish II: Passivisation
This study is the second of the writing series which investigates how the valency alternation strategy in Turkish works in terms of valency grammar. Valency alternation is the name of at least two different valency realization forms which can be called as lexical valency and grammatical valency, in which a verb that shares the same valency information and the same lexical meaning is often acquired by formative and syntactic processes. Passivization is one of the morphological processes that leads to a decrease in the lexical valecy information of verb. However, the only type of valency alternation that the passivization generates in the verbal valency information is not to reduce valency. It is seen that the passivation in Turkish sometimes reorganizes the valency of verb, and sometimes it keeps the valency of verb contrary to expectations, and even increases the valency of verb during passivation of the reflexive verbs. However, it cannot be said that the Turkish passivation strategy works regularly for all verb and verb classes. Some verb and verb classes are regularly passivated, while others do not allow for passivation or valency alternation, or they are bound and restricted to certain morphological and syntactic conditions.In this study, it has been suggested that Turkish passivization constraints stem from logical, syntactic and semantic valency of verbs. Which verbs and verb classes in Turkish which for reasons can not be passivizated and is limited are discussed in terms of valency grammar. Four (4) different types of valency alternation are identified which are caused by passivization. The relationship between the other voice categories in which the passivization resembles syntactically is described and some semantic generalizations have been achieved which can distinguish passive structures from other similar structures.
