102. 艾达把“发音”一词拼写错了，不过只是个笔误。

[误] Ida misspells the word "pronunciation", however, it is only a mistake of pen.

[正] Ida misspells the word "pronunciation", however, it is only a slip of the pen.

注：与 mistake（错误，误会，过失）相比，slip 更侧重于由于不经意或疏忽而造成的错误，所以“口误”一般译为 a slip of the tongue，同样，“笔误”就翻译成 a slip of the pen。
