Mandarin Pinyin has 21 initial consonants (声母) that open a syllable. They divide into labial, alveolar, velar, palatal, and retroflex series.
Initials like zh, ch, sh and r are retroflex consonants unique to Standard Mandarin among major Sinitic varieties.
Mandarin has 35 finals (韵母) — the vowel nucleus and any following nasal or rhotacised coda. They include simple vowels, diphthongs, and vowel-plus-nasal combinations.
The rhotacised final er (ㄦ) is unique to Mandarin; nasal finals -n and -ng are important for distinguishing many minimal pairs.
Mandarin is a tonal language with four lexical tones plus a neutral tone. Tone diacritics are written above the main vowel in Pinyin.
The same syllable with different tones conveys different meanings — for example, ma (妈) means "mother" in the first tone but "scold" (骂) in the fourth tone.
Bopomofo (Zhuyin Fuhao, 注音符號) is a phonetic script of 37 symbols used in Taiwan to represent the sounds of Mandarin Chinese [4].
Created in 1913, Bopomofo is used in Taiwan for teaching reading, in children's books, and in dictionary annotations. It covers the same initials and finals as Pinyin but with distinct symbols [5].
Mandarin is written in Chinese characters (Hanzi, 汉字) — logographic symbols each representing a syllable and a meaning. There are thousands of characters in use.
The characters shown here are among the most frequently used in everyday Mandarin writing, covering common verbs, pronouns, and function words.
Mandarin uses both Chinese numeral characters (一二三) and Arabic numerals (1 2 3) in everyday writing. Chinese numerals appear on formal documents, banknotes, and cultural contexts.
A distinctive feature is 万 (wàn), a unit for ten thousand — unique to the Chinese numeral system where numbers group in units of 10,000.
Mandarin Chinese uses full-width punctuation marks that differ from Western conventions. The ideographic full stop (。) and comma (,) are among the most recognisable.
Special angle brackets 《》 are used for book and publication titles, while 「」 marks direct quotations in traditional Chinese typography.
