Ü
letter of the Latin alphabet / From Wikipedia, the free encyclopedia
Ü (or ü) is a letter not used in English. It is commonly used to represent the sound [y]. Ü started as a u with an e above it. It comes from the German language and is used in the Turkic languages, such as Turkish. In German, ü can be replaced by the digraph ue respectively, if it is not available on the keyboard.
Mandated during Atatürk's Reforms in 1928, Turkey Latinized its alphabet formerly written in an Arabic script, using the extra German letters since they corresponded well to Turkic phonetic sounds.
