飽きる
あきる · akiru · JLPT N3 · verb-ichidan
to get tired of
🍚 飽 = 食 eat + 包 wrap: you've eaten your fill, so you're fed up
飽 first meant full or satisfied after eating. 飽きる carries that idea on: you've had so much of something that you're fed up with it. English uses the same food idea in fed up and had my fill.
