Where the spellings differ
- One initial, several letters: zh, ch and sh each name one Pinyin initial. Their Zhuyin counterparts are ㄓ, ㄔ and ㄕ.
- ü can lose its dots: qù contains ㄩ even though Pinyin writes u. After n and l, keep ü distinct from u.
- Shortened finals: shuǐ contains ㄨㄟ. Pinyin shortens uei to ui after an initial.
- No-initial spellings: yuè uses y, while its Zhuyin reading begins directly with ㄩ.
