A DIACHRONIC OVERVIEW TO VALENCY CHANGE OF POSTPOSITIONS IN TURKISH

In order to be meaningful units, words should interact with other units of a sentence and this interaction ought to be provided through various methods. All other necessary items for fulfilling the meaning of a word are called as determiners, while the relation of the word with a determiner is named as valency. From verbs to nouns, all free morphemes have valency. Postpositions, the subject matters of this article, require some suffix adjunctions to nouns, which constitute word groups (i.e. Senin i？in ya？？yorum; Eve kadar yürümek istiyorum). There are a lot of postpositions that have been used from Old Turkic to Turkish. Postpositions in question can interact with nouns which are used before those postpositions themselves; they also have some specific functions in a sentence. Both the meaning of a postposition and a bound morpheme, which has been used before a postposition, share a role in meeting the role of a function. Existence of bound morphemes varies with respect to periods. Even surveys of limited examples (？te, ？trü, kod？/koy？, asra/isre/esre, canib, bigi/gibi/kibi/kimi, saru/sar？ ve s？？aru/s？？ar？) show that any postpositions have at least one valency or even more, whereas all valency differs considering various historical periods of Turkish. This article aims to demonstrate valency of postpositions and diachronic valency changes as well as providing clarifications by way of evinced examples
