Quick Answer: What Is Fanqie?
Fanqie (反切, fǎn qiè) indicates a character’s pronunciation through two other characters: the first supplies the initial, while the second supplies the final and historical tone category. [1]
- Target: The character whose reading is being explained.
- First speller: The initial contribution.
- Second speller: The remaining syllable contribution and tone category.
- Limit: Modern Mandarin readings identify the characters but do not automatically recover an older pronunciation.
Read the entry as a structured sound note, not as an ordinary phrase made from the meanings of its characters.

An older dictionary may explain a sound without an alphabetic transcription. Its compact formula asks the reader to use two familiar syllables as pronunciation clues. Understanding the separate jobs of those clues is the first step; deciding their historical sound values is a further task.
Identify the Two Spellers and Their Different Jobs
The first character is often called the upper speller (反切上字, fǎn qiè shàng zì), and the second the lower speller (反切下字, fǎn qiè xià zì). “Upper” and “lower” label their order in the traditional formula; they do not mean higher and lower pitch. [1]
Take the initial contribution from the first, and the final and tone category from the second, within the sound system relevant to the source. The final is more than an English vowel letter: it concerns the part of the syllable after the initial. [1]
Do not blend the complete modern syllables together. Keep the formula’s roles separate from a convenient Pinyin label for each character. That distinction prevents the notation from becoming a misleading modern spelling exercise.
Read the Entry Dong, De Hong Qie
The documented formula 東,德紅切 refers to 東, now written 东 in simplified Chinese. The target’s modern Mandarin reading is dōng; the spellers are 德, dé, and 紅, hóng. These modern labels identify the characters rather than reconstructing the historical sound. [2]
| Written element | Job in the entry |
|---|---|
| 東 | Target character. |
| 德 | First speller: supplies the initial. |
| 紅 | Second speller: supplies the final and tone category. |
| 切, qiè | Closes the pronunciation formula. |
The historical database records 德紅 as the Guangyun spelling for 東 and places the target in the level-tone category, 平, píng. [2]
For a first encounter, identifying these four parts is already useful. The Chinese characters guide explains written units; here, the units describe pronunciation rather than forming a statement about virtue or red color.
Keep Historical Categories Separate from Modern Sounds
The same historical reference places 紅 in the level-tone category too, while distinguishing its initial category from that of 東. [3]
Modern Mandarin dōng and hóng carry different tones. That observation does not invalidate the historical entry: the old category labels and current Mandarin tones are different things to record. Do not replace an older tone category mechanically with the modern tone of its second speller.
Fanqie belongs to the historical study of Chinese pronunciation. A teaching overview connects its use in the Qieyun, dated 601, with the reconstruction of Middle Chinese. It is evidence for historical analysis, not a self-contained audio recording of a speaker. [4]
If a reference offers a reconstructed pronunciation, record which analysis it uses. This guide leaves a phonetic reconstruction out of the worked example so its structural lesson remains separate from a choice among reconstruction systems.
Record an Unfamiliar Entry in Three Parts
Use the following routine when making notes from an unfamiliar dictionary or commentary. Keep the source image available so you can revisit a doubtful character.
- Copy the entry: Record the target character, both spellers and the closing marker exactly as printed, together with the dictionary or commentary and its location.
- Label the two contributions: Mark the first speller as the initial source and the second as the final-and-tone source. Keep their modern reference readings in a separate field.
- Check the historical analysis: Consult a suitable phonological reference for the entry’s sound system. Leave a sound value unresolved when the available evidence does not establish it.
The guides to Classical Chinese function words and multiple character readings address adjacent reading problems. Preserve the actual gloss before deciding what it tells you about a particular occurrence.
FAQs About Fanqie
Does 切 belong to the target’s pronunciation?
In the worked formula, it closes the pronunciation note. Do not add it to the target as another spoken syllable.
Is fanqie the same as Pinyin?
No. Fanqie uses other characters as sound clues; Pinyin uses a Roman-letter system for Mandarin.
Does one worked example decode every entry?
No. Different sources and historical readings require appropriate reference evidence. Recognizing the notation is the beginning of that work.
