Ü

Ü (lowercase ü) is a Latin script character composed of the letter U and the diaeresis diacritical mark. In some alphabets such as those of a number of Romance languages or Guarani it denotes an instance of regular U to be construed in isolation from adjacent characters with which it would usually form a larger unit; other alphabets like the Azerbaijani, Estonian, German, Hungarian and Turkish ones treat it as a letter in its own right. In those cases it typically represents a close front rounded vowel .

Although not a part of their alphabet, Ü also appears in languages such as Finnish and Swedish when retained in foreign proper names like ''München'' ("Munich"). A small number of Dutch and Afrikaans words employ the character to mark vowel hiatus (e.g. ''reünie'' /reːyˈni/ ("reunion"), a loanword marked with diaeresis to suppress the native reading of ''eu'' as a digraph pronounced /øː/).
