Meaning of Substitute

[Tom]

Hi everybody

It just occured to me that I confuse the word SUBSTITUTE.

1, He substituted the word GOOD for NICE in his essay.

(which word did he use?)

2, Tea was substituted for coffee at the party.

(what was taken at the party)

3, The beautiful sofa was substituted for an ugly chair in
the room.

Is substitute WITH correct? Or always FOR?

Thanks in advance

Tom

Originally was "good" then it was changed to "nice"The same parallel in the other sentences."Substitute" is used with the preposition "for"
