普通话 (pǔ tōng huà) literally means 'common speech' — 普 (pǔ) means 'universal' or 'general', 通 (tōng) means 'common' or 'shared', and 话 (huà) means 'speech' or 'language'. Together, they refer to Standard Mandarin Chinese: the official national language of China, based on the Beijing dialect and standardized in pronunciation, vocabulary, and grammar. It is used in education, government, media, and formal communication across mainland China, Taiwan, and Singapore.

While many regional dialects (like Cantonese or Shanghainese) remain widely spoken at home or locally, 普通话 is required for school instruction, national exams, and interregional communication. It’s also the variety taught to most foreign learners of Chinese. Note that although often called 'Mandarin' in English, 普通话 specifically denotes the standardized form — not all Mandarin dialects qualify as 普通话.
