Language reform and modern Turkish

After the foundation of the modern state of Turkey and the script reform, the Turkish Language Association (TDK) was established in 1932 under the patronage of Mustafa Kemal Atatürk, with the aim of conducting research on Turkish. One of the tasks of the newly established association was to initiate a language reform to replace loanwords of Arabic and Persian origin with Turkish equivalents. By banning the usage of imported words in the press, the association succeeded in removing several hundred foreign words from the language. While most of the words introduced to the language by the TDK were newly derived from Turkic roots, it also opted for reviving Old Turkish words which had not been used for centuries. In 1935, the TDK published a bilingual Ottoman-Turkish /Pure Turkish dictionary that documents the results of the language reform.

Owing to this sudden change in the language, older and younger people in Turkey started to differ in their vocabularies. While the generations born before the 1940s tend to use the older terms of Arabic or Persian origin, the younger generations favor new expressions. It is considered particularly ironic that Atatürk himself, in his lengthy speech to the new Parliament in 1927, used the formal style of Ottoman Turkish that had been common at the time amongst statesmen and the educated strata of society in the setting of formal speeches and documents. After the language reform, the Turkish education system discontinued the teaching of literary form of Ottoman Turkish and the speaking and writing ability of society atrophied to the point that, in later years, Turkish society would perceive the speech to be so alien to listeners that it had to be "translated" three times into modern Turkish: first in 1963, again in 1986, and most recently in 1995.

The past few decades have seen the continuing work of the TDK to coin new Turkish words to express new concepts and technologies as they enter the language, mostly from English. Many of these new words, particularly information technology terms, have received widespread acceptance. However, the TDK is occasionally criticized for coining words which sound contrived and artificial. Some earlier changes—such as bölem to replace fırka, "political party"—also failed to meet with popular approval (fırka has been replaced by the French loanword parti). Some words restored from Old Turkic have taken on specialized meanings; for example betik (originally meaning "book") is now used to mean " script " in computer science.

Some examples of modern Turkish words and the old loanwords are:
