Cantonese language

Dialects: Standard Cantonese (Guangzhou/Hong Kong), plus regional varieties such as Taishanese (Toisan), Wuzhou (Guangxi), and Zhongshan.

Geographic Reach: A primary language of Hong Kong and Macau; widely spoken across Guangdong and eastern Guangxi, and in overseas Chinese communities in Southeast Asia and around the world.

Linguistic Notes:

  • Cantonese is a Sinitic language, written left-to-right in Chinese characters. Traditional Chinese is standard in Hong Kong and Macau.

  • A tonal system with six or more lexical tones and preservation of final stop consonants -p, -t, and -k.

  • Diglossia is common: formal writing typically uses Standard Written Chinese, while daily communication relies on spoken Cantonese; vernacular written Cantonese appears in media and online.
