The direction of the change in question is both from verbal language to written language and from written language to verbal language. Changes are studied in linguistics by two different types of research approaches, namely diachronic and synchronic.
This qualitative study using the quantitative data collection tool focused on the phenomenon of synchronic change. The aim of this descriptive study is to reveal to what extend the reductions in verbal Turkish has reflected on written language.
