Pinyin Explained: Initials, Finals, Tones and Spelling
Hanzi Grove · 2026-11-09
Pinyin is the standard system for writing the sounds of Mandarin Chinese in the Latin alphabet. Each syllable has up to three parts: an initial (the starting consonant), a final (the vowel part, sometimes ending in n or ng) and a tone mark, so in hǎo, h is the initial, ao is the final and the mark ˇ shows the third tone.
Pinyin uses familiar letters, but several of them do not sound the way an English speaker expects. This guide covers the initials, the finals, how to place tone marks, the spelling rules for ü, y, w and apostrophes, and the mistakes English speakers make most often.
How a pinyin syllable works
Mandarin has a fairly small set of syllables. Almost every one follows the same pattern:
initial + final + tone
- 妈 mā = m + a + first tone
- 好 hǎo = h + ao + third tone
- 学 xué = x + üe + second tone (written ue after x; see the ü rule below)
- 爱 ài = no initial + ai + fourth tone
Some syllables have no initial, but almost every syllable has a final.
The initials
There are 21 initials. Many sound close to English, but a few need care.
| Group | Initials | Notes |
|---|---|---|
| Lips | b, p, m, f | b is like the p in “spin”; p is like “pin” with a puff of air |
| Tongue tip | d, t, n, l | d is unaspirated, t has a puff of air |
| Back of tongue | g, k, h | h is rougher than English h, closer to the ch in Scottish “loch” |
| Front of tongue | j, q, x | Tongue flat behind the lower teeth, lips spread |
| Curled tongue | zh, ch, sh, r | Tongue tip curled up and back |
| Tongue tip, teeth | z, c, s | z like “ds” in “beds”, c like “ts” in “cats” |
The key idea is aspiration, not voicing. In pinyin, b, d and g are not fully voiced like English b, d and g. They are plain sounds with no puff of air. Their partners p, t and k have a strong puff. Hold your hand in front of your mouth: you should feel air on p, t, k, q, ch and c.
The hard ones for English speakers
- q sounds close to “ch” in “cheese”, with the tongue flat. 去 (qù, to go) is not “kew”.
- x sounds close to “sh” in “sheep”, with the tongue flat. 谢 (xiè) is not “zee-eh”.
- c sounds like “ts”. 菜 (cài, dish) is like “tsai”.
- z sounds like “ds”. 在 (zài, at) is like “dsai”.
- zh sounds close to “j” in “jar”, with the tongue curled back. 中 (zhōng, middle).
- r is between English “r” and the “s” in “pleasure”. 人 (rén, person).
The finals
Finals are the vowel part of the syllable. They can be single vowels, vowel combinations, or vowels ending in n or ng.
| Type | Finals |
|---|---|
| Single vowels | a, o, e, i, u, ü |
| Combinations | ai, ei, ao, ou, ia, ie, iao, iou, ua, uo, uai, uei, üe |
| Ending in n | an, en, in, ian, uan, uen, ün, üan |
| Ending in ng | ang, eng, ing, ong, iang, iong, uang, ueng |
| Special | er |
Some vowels sound different from English:
- e on its own is a soft “uh” sound, not “eh”. 的 (de), 喝 (hē, to drink). In ie and üe, though, e sounds like the “e” in “yes”: 谢 (xiè).
- i after z, c, s, zh, ch, sh and r is not “ee”. It is a buzzing continuation of the consonant. 是 (shì) does not rhyme with “she”. 四 (sì, four) does not sound like “see”.
- ian sounds like “yen”, not “yan”. 天 (tiān, sky) is close to “tyen”.
- ui (from uei) sounds like “way”. 对 (duì, correct).
- iu (from iou) sounds close to “yo”: 六 (liù, six) is close to “lyoh”.
- un after most initials (from uen) sounds like “wun”. 春 (chūn, spring).
- ong has a vowel like the “o” in “book”, not “long”.
Tone marks
Mandarin has four tones and a neutral tone. Pinyin marks them with symbols over the main vowel:
| Tone | Mark | Example |
|---|---|---|
| 1st | ā | 妈 mā |
| 2nd | á | 麻 má |
| 3rd | ǎ | 马 mǎ |
| 4th | à | 骂 mà |
| neutral | no mark | 吗 ma |
Where does the tone mark go?
Use this order:
- If there is an a or an e, the mark goes on it: hǎo, xiè, mèi.
- If the final is ou, the mark goes on the o: dōu, gǒu.
- Otherwise, the mark goes on the last vowel: liù, guì, duō.

Spelling rules
Pinyin has a few spelling rules that change how finals are written. They do not change the sound. They exist so syllables are easy to separate.
Rule 1: y and w at the start of a syllable
When a final beginning with i, u or ü has no initial, it is spelled with y or w.
- i → yi, in → yin, ing → ying
- ia → ya, ie → ye, iao → yao, iou → you, ian → yan, iang → yang, iong → yong
- u → wu, ua → wa, uo → wo, uai → wai, uei → wei, uan → wan, uen → wen, uang → wang, ueng → weng
- ü → yu, üe → yue, üan → yuan, ün → yun
So 有 is yǒu (not iǒu), 我 is wǒ (not uǒ), and 月 is yuè (not üè). See 月.
Rule 2: when ü loses its dots
After j, q, x and y, ü is written as u, because u can never follow these letters. The sound is still ü.
- 去 qù, 学 xué, 句 jù, 鱼 yú all have the ü sound.
After n and l, the dots stay, because both nu and nü exist: 女 nǚ (woman) and 努 nǔ (effort) are different. The same goes for 绿 lǜ (green) and 路 lù (road).
Rule 3: shortened finals
Three finals drop a letter after an initial:
- iou → iu: l + iou = liù (六)
- uei → ui: d + uei = duì (对)
- uen → un: ch + uen = chūn (春)
The full sound is still there. That is why liù has a faint “o” in it and duì sounds like “dway”.
Rule 4: the apostrophe
When a syllable starting with a, o or e follows another syllable in the same word, put an apostrophe between them so the boundary is clear.
- 西安 Xī’ān (the city) is two syllables. Without the apostrophe, xian could be read as one syllable, as in 先 (xiān, first).
- 女儿 nǚ’ér (daughter)
- 天安门 Tiān’ānmén
Rule 5: names and capitals
Proper names are capitalised: 中国 Zhōngguó, 北京 Běijīng. Words are usually written as units, not syllable by syllable: péngyou, not péng you. See the 中国 word page.
Common pinyin mistakes
- Reading pinyin as English. “Xi” is not “zee” and “qi” is not “kee”. Learn the six hard initials above first.
- Ignoring aspiration. b/p, d/t, g/k, j/q, zh/ch and z/c are pairs that differ by a puff of air. Mixing them changes the word.
- Missing the hidden ü. In ju, qu, xu and yu, the vowel is ü, not u.
- Saying “ee” after z, c, s, zh, ch, sh, r. In zi, ci, si, zhi, chi, shi and ri, the i is not “ee”.
- Dropping tone marks. Learning pinyin without tones means learning each word twice. Always learn the tone with the word.
How to practise pinyin
Spend your first few days on the sounds, then move on to real words. Pinyin is a tool for learning characters, not a replacement for them.
On Hanzi Grove, every word in the HSK lists shows its pinyin with tone marks and plays its audio. A good routine is to listen to a word, write its pinyin, then check. Start with HSK 1, group 1, which includes 你好 and 谢谢. When you are ready for characters, the beginner path explains strokes, patterns and radicals.
Frequently asked questions
How long does it take to learn pinyin?
Most learners can read pinyin within a week or two of daily practice. Hearing and producing every sound accurately, especially tones, takes longer and improves with each word you learn.
Is pinyin used by native speakers?
Yes. Pinyin is used in mainland China to teach children to read and to type Chinese on phones and computers. Taiwan also uses Zhuyin (Bopomofo).
Can I learn Chinese with pinyin only?
Only for speaking and listening at the start. To read signs, books or exam papers, you need characters. Pinyin helps you learn them faster.
Why is ü written as u after j, q and x?
Because u never follows j, q or x in Mandarin, so there is no risk of confusion. The dots are only kept where both sounds exist, after n and l.
