Expressing "no wonder"

怪不得 (guàibude) can be used to express that the speaker finds something unsurprising. It can be used alone or in a variety of different structures, as shown below. 难怪 (nánguài) is another way to express exactly the same thing.

Structure

怪不得 is used to convey the speaker's lack of amazement at a situation, having recently acquired some new information that in his opinion explains it. It can be replaced with 难怪 in the structure without altering its meaning.

Reason ，怪不得 / 难怪 + Observation

or

怪不得 / 难怪 + Observation ，原来 + Reason

the Other Meaning of 难怪

This usage is definitely less common, but sometimes 难怪 is a combination of the 难 + Verb pattern and the verb 怪, meaning "to blame." In this case, the meaning is totally different. Although it's not as common and you shouldn't need to worry about it too much, we include it here because if you ever run into and think that 难怪 can only ever have one meaning, it can totally throw you for a loop.

A few common examples:

• 这也 难怪 他 ，他 这么 小 。 Zhè yě nánguài tā, tā zhème xiǎo.Don't blame him. He's so young.
• 这也 难怪 大家 ，是 我们 通知 晚 了 。Don't blame everybody. It was a short notice.
• 这 也 难怪 ，你们 第 一 次 来 ，还 不 了解 这里 的 风俗 。Zhè yě nánguài, nǐmen dì-yī cì lái, bù liǎojiě zhèlǐ de fēngsú.Don't blame yourselves. It's your first time here, and you don't understand the customs.

When used in this way it expresses that the speaker assigns no blame in the situation he is describing. Sometimes the specific person undeserving of blame is mentioned directly after 难怪, as in the first two examples. Often however the context makes clear who this person is and this is not necessary, as in the third example.
