Please explain the use of which and that??
I am not a teacher.
Some more information on this topic which I found through google search with more examples.
If the phrase is essential to the meaning or context of the sentence, then we use THAT.
If the phrase is not essential to the meaning or context of the sentence, then we use WHICH.
Examples:
1. I quickly saved the document
that I had been working on all morning.
The information here is essential in letting the reader know which document the narrator saved.
2. I made sure to grab my warm coat,
which was hanging in the closet, before I left for the meeting.
The information here is not essential in letting the reader know that the coat was grabbed.
3. The storm,
which was approaching us quickly, inspired a fear
that stayed with us all afternoon.
In the first phrase, "which was approaching us quickly" is not necessary information; it adds the speed of the
storm. "That stayed with us all afternoon" is essential in understanding the type of fear "they" experienced.
