Not given enough food over a long stretch of time, so that it shows on the body — thin, weak, small for their age. You use it about people and very often about animals: an underfed dog, underfed cattle, underfed children in a poor district.

Not given enough food沒有得到足夠的食物 over a long stretch of time長期以來，so that這樣一來 it shows on the body身體上就看得出來 — thin, weak, small for their age又瘦又弱、年紀看起來比同齡小。You use it你會用它 about people來講人 and而且 very often about animals也很常講動物: an underfed dog吃不飽的狗、underfed cattle吃不飽的牛、underfed children in a poor district貧困地區吃不飽的小孩。

The important part is that it points a finger at someone else. Being underfed means someone else was supposed to feed you and did not do it well enough — parents, an owner, a government, a school.

The important part重要的一點 is是 it points a finger at someone else這個字把責任指向別人。Being underfed用這個字 means代表 someone else別人 was supposed to feed you應該要餵飽你 and而 did not do it well enough卻沒有做好 — parents父母、an owner飼主、a government政府、a school學校。

That is what separates it from 'hungry', which is just a feeling you have right now and passes with lunch, and from 'thin', which may be nothing more than the body a person happens to have. It also describes a lasting state, not one skipped meal.

That is what separates it這就是它不一樣的地方 from 'hungry'跟 'hungry'，which is just a feeling you have right now hungry只是你當下的感覺 and而且 passes with lunch吃頓飯就過去了, and而 from 'thin'跟 'thin' 也不同, which may be nothing more than the body a person happens to have thin可能只是一個人天生的體型而已。It also describes它講的是 a lasting state一種持續的狀態, not one skipped meal不是少吃一頓飯而已。

People do use it lightly and jokingly about themselves — 'you're not exactly underfed' when someone complains about their weight — but the plain meaning is a serious one.

People有些人 do use it lightly and jokingly也會輕鬆開玩笑地用它 about themselves來講自己 — 'you're not exactly underfed'「你也不算吃不飽啊」 when someone complains about their weight當有人抱怨自己的體重時 — but but平常的意思 the plain meaning is a serious one卻是很嚴肅的。
