The name Bopomofo comes from the first four symbols: ㄅ ㄆ ㄇ ㄈ. The system is also called Zhuyin (注音). It is widely used for learning Mandarin and entering Chinese text in Taiwan.
Our chart groups the 37 symbols into 21 initials, 3 medials and 13 other finals. This is a study arrangement: the three medials also belong to the broader group of 16 rhyme symbols.
Some syllables need just one symbol; others combine two or three. A tone belongs to the whole syllable. Many characters can share a reading, which is why a keyboard offers a choice of characters.
