noun
flash of inspiration; insight; flair
Refers to a sudden creative idea, clever thought, or witty remark that comes to mind. Often used in contexts of problem-solving, art, or conversation.
いいひらめきが浮かんだ。
A good idea flashed into my mind.
彼のジョークにはひらめきがある。
His jokes have a flash of wit.
noun
Describes the visual effect of something like a flag or cloth waving in the wind. Less common than the inspiration sense.
旗のひらめきが遠くから見えた。
The fluttering of the flag was visible from afar.
Derived from the verb ひらめく (to flash, to flutter). The inspiration sense likely comes from the metaphor of a sudden flash of light.
