not able to be predicted
If something is unpredictable, you cannot know what will happen with it before it happens.
用法模式：
an unpredictable [situation / event / result]
常见错误：
Learners sometimes use *unpredictable* when they only mean *surprising*. *Unpredictable* suggests that you cannot reliably know in advance what will happen, not just that something is unusual. Another common error is misspelling it as *unpredictible*; the correct form is *unpredictable* with *-able*.
