Cách sử dụng
The word 'causal' is used to describe the connection between two things or events - where one thing is the cause of the other thing happening. For example, if you eat too much junk food, the causal effect could be that you become unhealthy. It is useful to use 'causal' when you want to explain why something happened or why someone did something. However, you should be careful when using this word as it is a little more technical and should be used in appropriate situations - not all situations require the use of 'causal'.
