刮
guā · HSK 6
to blow (of the wind)
🌬️ tongue + knife: wind so sharp it scrapes like a blade
The left side 舌 means tongue, the right side 刂 is the knife radical. A gusting wind scrapes and cuts across exposed skin, just as a blade would.
刮 — tongue 舌 + knife 刂
A semantic-phonetic compound: 刂 (knife) gives the meaning of scraping or shaving, while 舌 supplies the sound. The original sense was to scrape with a blade, later extended to wind 'scraping' surfaces, as in 刮风 (to blow strongly).
