Shanghainese

The Shanghainese language, also known as the Shanghai dialect, or Hu language, is a variety of Wu Chinese spoken in the central districts of the city of Shanghai and its surrounding areas. It is classified as part of the Sino-Tibetan language family. Shanghainese, like the rest of the Wu language group, is mutually unintelligible with other varieties of Chinese, such as Mandarin. Shanghainese belongs to a separate group of the Taihu Wu subgroup. With nearly 14 million speakers, Shanghainese is also the largest single form of Wu Chinese. Since the late 19th century, it has served as the lingua franca of the entire Yangtze River Delta region, but in recent decades its status has declined relative to Mandarin, which most Shanghainese speakers can also speak. Like other Wu varieties, Shanghainese is rich in vowels and consonants, with around twenty unique vowel qualities, twelve of which are phonemic. Similarly, Shanghainese also has voiced obstruent initials, which is rare outside of Wu and Xiang varieties. Shanghainese also has a low number of tones compared to other languages in Southern China and has a system of tone sandhi similar to Japanese pitch accent.
