Can “attributive clause” and “noun clause” be exchanged, excluding appositive clause?
For example:
Remind the clients what maintenance advice they should follow.(object clause)
Remind the clients the maintenance advice that they should follow.
I wonder where she comes from. (object clause)
I wonder the place that she comes from.
Whoever says that is a liar.(subject clause)
Anyone who says that is a liar.
That is what he meant.(predicative clause)
That is the meaning that he meant.
Thank you very much!
