Cách sử dụng
The expression "a slip of the pen/tongue" is used to describe a mistake someone makes when they are writing or speaking, often by accidentally writing or saying the wrong word. For example, if someone meant to write "cat" but accidentally wrote "car", they might say "Oops, that was just a slip of the pen!" Similarly, if someone meant to say "goodbye" but accidentally said "hello" instead, they might say "Sorry about that, it was just a slip of the tongue." So, the expression is used to explain that the mistake was unintentional and not done on purpose.
