The current study examined four different orthography guides prepared by Turkish Language Society between 1996 and 2012. These orthography guides included different spellings in words with capital letters, compound words, abbreviations, and some other words. The spelling differences defined were analyzed in groups. Different spelling preferences in abbreviations were presented in a table. The issues that these orthographic modifications may involve in Turkish language teaching were discussed. The orthography unity in words and abbreviations was emphasized and what to do in order to provide unity was put forward in conclusion and suggestions section.
