輝く
かがやく · kagayaku · JLPT N3 · verb-godan
to shine
💎✨ 輝 = 光 light + 軍 army: light flashing off an army's armour
The kanji puts 光 (light) beside 軍 (army). In old Japanese the word was kakayaku, with no voiced sounds, so the related verb kagayakasu means to make something shine. Ka-ga-ya-ku: three soft syllables before the final -ku verb ending.
