Turkish is one of the oldest functional languages. It is spoken by about 100 Million people living in Turkey, former Soviet republics, China, parts of the Middle East and the Balkans. It belongs to the Turkic branch of the Altaic family of languages.
All Turkish infinitives end in -mak or -mek. Like in the Finnish language, the vowel harmony plays a big role on constructing the inflected forms. Compare for instance the forms of olmak and ekmek!
