Today i’m going to teach you 4 ways to say “You are welcome” in Italian.
今天我要教大家说“不客气”的4种不同方式。

1. Prego
Prego is basic and most used way to say “you are welcome” in Italian. And this should be like your first choice.
Prego是最基本也是最常用的表达方式。当你想回答“谢谢”时，这可以是你首选。

2. Nessun problema/Non c’è problema

The second is as you say “No problem” in English. This is the typical expression that is adapted to various situations. And if someone tells you thank you, you can answer “Nessun problema”. It actually means “Prego”.
这相当于英语中的No problem，适用于各种不同的情形。和prego意思一样，可以自由选择说哪个。

3. Figurati (Si figuri)

You just say “Figurati” when you are talking to your friend or someone you know.
这个可以对朋友和熟人说。

The formal form will be “Si figuri”. You can say it to someone you don’t know.
For example, if you are the waitress or the waiter in a restaurant and the client tells you “thank you”, you answer “Si figuri” because you don’t know the person. So you cannot say “figurati” unless he’s a friend of yours.
这个的正式形式是Si figuri，你可以对着你不认识的人说，表示尊敬。举个例子，假如你是一个餐馆的服务员，然后有个客人对你说谢谢，你可以回si figuri。因为你不认识这个客人，他不是你的朋友。

It’s basically means prego.
简单来说，这个词组的意思和prego也是一样的，都是不客气。

4. Non c’è di che

It is the abbreviation for “Non c’è di che ringraziare” which means there’s nothing to thank for. We don’t really say “Non c’è di che ringraziare”. We cut off “ringraziare”. And we just say ““Non c’è di che”. It’s a fixed expression. You just say it as it is.
这个词组是“Non c’è di che ringraziare” 的缩写，可以译为“没啥好谢的”。但注意我们从来不说“Non c’è di che ringraziare”，从来只说省略形式。

Prego另一种用法

Let’s take again that example of the waitress or waiter. For example, you take the meal to the client and you say “Prego”. It means like “Here you are”.
If you bring something to someone and you say “prego” like “Here you go” “Here it is”.
prego还有另外一个意思，还是举那个餐厅服务员的例子，假如你端菜给客人，你递给客人的同时说Prego,这时prego的意思是“给您，慢用”（解释为英语中的here you are更容易理解。）或者，在你递给别人东西时，你都可以说prego。
