    Thumbs up difference between "That is why" and "which is why"

    What is the difference between "that is why" and "which is why"?

    -I couldn't pass the course, which is why I have to take it again.

    In such sentences, which directly refers to the sentence preceding it, and we should put a comma before it.
    We can't start a new sentence by which.


    -I couldn't pass the course. That is why I have to take it again.
    In this one, that, even though it is semantically related to the sentence before it, canstart a new sentence and isn't structurally dependent on the preceding sentence.


    I don't find it necessary to get into more detail.

    Thanks a ton for the answer!!

    I was basically talking about speaking English.

    As per your answer, I see that meaning point of view there is no difference, but in the writing it makes a difference.

    Like putting the comma in case of which.

    So, I guess, I need to make sure that while speaking it is always better to use that is why.

    what do you say?

    It's probably more likely to be used that way, but 'which is why' is also possible.
