to brag about
🏆 夸 boast + 耀 shine = brag so loud you dazzle; flaunting that glitters
夸 means to exaggerate or boast; 耀 means to shine or dazzle (same 耀 as in 闪耀, to glitter). Together: to brag in a way that shows off and dazzles others, i.e. to flaunt.
夸 — big 大 + on/in 亏 (phonetic)
夸 is a semantic-phonetic compound: 大 ('big') gives the meaning of exaggeration or grandness, while 亏 supplies the sound. Originally it meant to boast or speak grandly, and it still carries senses of 'brag' and 'praise' in modern Chinese.
