晒
shài · HSK 4
soak up sun
☀️ 晒 = 日 (sun) + 西 (west); afternoon western sun bakes things dry
The radical 日 means sun; 西 (west) hints at the late-day sun that dries laundry on the line. Extended sense 'cold-shoulder' comes from leaving someone out 'in the sun' — ignored and exposed.
晒 — sun 日 + west 西 (phonetic)
A semantic-phonetic compound. The 日 (sun) component gives the meaning of sunlight or drying in the sun, while 西 (xī) suggests the pronunciation. Originally written 曬, the character refers to exposing things to sunlight, and by extension now means to show off or share publicly.
