綺麗
きれい · kirei · JLPT N5 · na-adj
tidy
✨🧼 kirei sounds like key-ray: a key polished till it throws a ray = pretty, clean
One word covers both pretty and clean: in Japanese, tidy is beautiful. 綺 is fine patterned silk and 麗 is lovely, so the kanji say silk-lovely. It is a na-adjective despite ending in い: kirei na heya = a clean room.
