How it is used
- The "no wonder / that explains it" reaction on learning a cause - 怪不得他没来，原来病了 (guàibude tā méi lái, yuánlái bìng le) no wonder he didn't come, turns out he's sick.
- Often pairs with 原来 (yuánlái, it turns out) in the follow-up clause.
- A second sense means "can't blame (sb)": 这怪不得你 (zhè guàibude nǐ) this isn't your fault - context decides which reading.
