Productivity of Derivational Affixes in Surani Kurdish Language: Corpus-based Approach.

The present research has investigated the production of derivational affixes in the Surani Kurdish language, based on the corpus of “Kurdpress”. In morphology, the productivity of a suffix was expressed as the number of new words created by that suffix. In this way, the present research has investigated the frequency of the derivational affixes of the Kurdish language in the final position of the word, based on a corpus approach. In the first step of this research, a list of Kurdish suffixes was identified. Then, by using web crawling programming in Python language, the required data was prepared from the Kurdpress news network. The measuring criterion used for the productivity of each of these suffixes is based on the criterion of the p value. Finally, it was most the among were” چیی د ن، د ،ییند ی د ،یی ” words the that determined productive suffixes in the Kurdish language with a productivity rate of more than 50%. Among the other things discussed in this study is the difference between the concept of productivity and the importance that an affix assigns to itself. The importance of an affix is known in the number of words that are used in the vocabulary list of the language. [ABSTRACT FROM AUTHOR]
