耀眼
yào yǎn · HSK 7
dazzling
✨👁️ 耀 = shine/glare + 眼 = eye, so 耀眼 is light so bright it hits the eyes
耀 means to shine or glare; 眼 means eye. Together they describe something dazzling, literally eye-shining. Pronounced yào yǎn, both syllables fall then dip, matching the snap of a sudden bright flash.
眼 — eye radical 目 + 艮 (phonetic)
眼 is a semantic-phonetic compound. The left side 目 means 'eye' and gives the meaning, while 艮 on the right supplies the sound. Originally referring to the eyeball, it broadened over time to mean 'eye' generally and, by extension, 'a hole' or 'key point'.
