About
The character 唰 is a phono-semantic compound with the mouth radical 口 on the left, indicating sound, and the phonetic component 刷 on the right, meaning "to brush" and providing the "shuā" pronunciation. This combination forms an onomatopoeia for a sharp, swift rustling or swishing noise. It mimics the sound of quick movements, such as a bird taking flight, a curtain being drawn, or an object slicing through the air, and is primarily used as a descriptive sound word in modern writing.
