食欲

Think of it as two parts: '食' (shí) means food, and '欲' (yù) means desire. So, it's a 'desire for food' or appetite. You can imagine someone craving delicious food when you see '食欲'.

You would say, '我食欲很好' (Wǒ shíyù hěn hǎo). This literally means 'My appetite is very good'.

For that, you can say, '我没有食欲' (Wǒ méiyǒu shíyù) or '我食欲不佳' (Wǒ shíyù bù jiā). '不佳' (bù jiā) means not good, or poor.

No, '食欲' is specifically for food. If you want to talk about desire in a general sense, you'd use a different word like '欲望' (yùwàng).

It's a neutral term, so you can use it in both formal and informal conversations. It's a standard word for appetite.

Yes, '增进食欲' (zēngjìn shíyù) means 'to increase appetite', and '开胃' (kāiwèi) means 'to whet the appetite', which is often used in relation to appetizers.

You could ask, '你食欲怎么样?' (Nǐ shíyù zěnmeyàng?), which means 'How is your appetite?' or 'Do you have an appetite?'

'饿' (è) means hungry, which is a physical sensation. '食欲' is the desire to eat, which can be present even if you're not starving. For example, you might not be starving but still have an appetite for dessert.

Yes, you can say '这道菜能刺激我的食欲' (Zhè dào cài néng cìjī wǒ de shíyù), meaning 'This dish can stimulate my appetite'.

You would typically use '食欲不振' (shíyù bù zhèn). '不振' (bù zhèn) means lack of vigor or being low, so it conveys a poor or diminished appetite often associated with not feeling well.
