changeable 和 unpredictable 的差別在哪裡？如果不好說明，請提供一些例句。

changeable means that it is likely to change throughout the day. For example: "it was sunny this morning and now it's pouring rain. The weather is really changeable today." Also: " they are predicting that it will snow this evening even though it's sunny and warm right now." "I'm not surprised, the weather has been really changeable recently."

unpredictable means that the weather cannot be anticipated. For example: " I had planned to have a barbecue today because the forecast said it would be clear skies but it's raining. It's a shame the weather is so unpredictable"

The meaning is quite similar. the main difference is that changeable weather can be predicted as it just means that it will change but unpredictable means that it can't be predicted for whatever reason. This reason could be that it is too changeable or something else like the weather report is inaccurate or their is a freak occurrence.
