This corpus-based study investigated the levels at which Turkish newspaper writers have accepted economic terms that were made official by the Turkish Language Society (TDK) between the years 1995 and 1998 in its attempt to purge Turkish of European and English economic terms. The study found that writers used loan terms more frequently than the official terms in their newspaper articles. In an additional survey, writers reported a need for planning for the use of economic terms in Turkish. This study contributes to terminology and language planning attempts in Turkey and elsewhere, such as efforts to invent more acceptable terms and to find efficient ways of implementing their use.
