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 Some earlier changes—such as ' to replace ', "political party"—also failed to meet with popular approval (' has been replaced by the French loanword '). Some words restored from Old Turkic have taken on specialized meanings; for example "" (originally meaning "book") is now used to mean "script" in computer science.
