Hungry
I'm Hungry
expression
When your belly has decreased in the amount of stuff inside it, you become hungry.
腹が減った is a casual way of saying I'm hungry in Japanese, often with a bit of a rough or masculine tone.
The reading is 腹 plus 減る put together. With these two combined, you have はらがへった.
In casual speech, you might hear 腹減った without the が more often. The version with が is more common in writing or fixed expressions like 腹が減っては戦ができぬ (you can't fight on an empty stomach).
腹が減ったなぁ。何か作ってよ。
I'm hungry. Can you make something for me?
腹が減ったよ〜！でもお弁当もう全部食べちゃった。
I'm starving! But I already ate my bento.
さっき食べたばっかなのに、もう腹が減ったの？
You just ate a little while ago, and you're already hungry again?
腹が減ったな。この件については、昼飯を食べながら話さないか？
I’m hungry. Would you like to continue this over lunch?
