TDK

A shortening for a Turkish corporation called Türk Dil Kurumu (Turkish Language Corporation). It works for creating new Turkish words instead of using foreign words like tren(train),abajur(lampshade) etc.

TDK'nın alternatif kelimesine yeni bir alternatif çıkardığını öğrendim. Ay,pardon.
I learned that TDK has created a new alternative for the word "alternative". Oops,sorry.
