### Summary

Wu is a major Sinitic language group centered on Shanghai, Zhejiang, and Jiangsu, including Shanghainese. Its rich tonal system and preserved Middle Chinese voiced initials distinguish it sharply from Mandarin.

### Description

## Historical Evolution
Wu varieties developed from ancient Jiangdong speech, retaining more Middle Chinese voiced obstruents than Mandarin. Shanghainese rose in prestige with Shanghai's commercial boom in the 19th–20th centuries. Mandarin promotion policies classify Wu as a dialect, though linguistically it is often mutually unintelligible with Putonghua.

## Phonology
Shanghainese has a complex tone system with register and length splits; some analyses count eight or more surface tones. Voiced obstruents remain phonemic in many Wu lects. Tone sandhi rules apply across phrases, sometimes neutralizing distinctions present in citation forms.

## Syntax
Wu shares SVO basics with other Sinitic languages but uses distinct particles, pronominal forms, and aspect markers. Shanghainese employs a unique third-person pronoun (伊) and rich diminutive suffixes. Code-switching with Mandarin is ubiquitous in urban youth speech.
