J̌, called J with caron, is a letter of the Latin alphabet, derived from J with the addition of a caron (háček). It is used in some phonetic transcription schemes, e.g. ISO 9, to represent the sound. It is also used in the Latin scripts or in the romanization of various Iranian and Pamir languages, Armenian, Georgian, Berber/Tuareg, and Classical Mongolian. The letter was invented by Lepsius in his Standard Alphabet on the model of š and ž to avoid the confusion caused by the ambiguous pronunciation of the letter j in European languages.
