Would it be correct to write The gate which opens or the gate that opens?

Answer 1

well the answer is none of them because you can also say the gate which open and you can also say the gate that open so you can write both of them so it dot really matter that much if u are used to saying which you can say that if you used to saying that you can say that.

You need more of the sentence to determine which word is correct. If the sentence you're writing does not need the clause that is being connected, then you should use which. If it does need the clause for the sentence to be completely understood, then use that. Here is an example: The gate that opens is the one on the left. In this case, you need the clause in order to differentiate between two or more gates. The gate which is very old is a beautiful wooden structure. In the second example, you don't need to know that the gate is old for the sentence to be understood.

Answer 2

Both "The gate which opens" and "The gate that opens" are correct constructions. However, "The gate that opens" is more commonly used and is considered more concise and direct.
