In English, an indirect statement is a subordinate clause that relates some kind of statement indirectly. In other words, it talks about a statement from a retelling instead of a direct quote. It is the opposite of a direct statement. So while the following sentence is a direct statement:
He said, "I am going to the store tomorrow."
The following statement would be the same thing in an indirect form:
He told me that he was going to the store tomorrow.
To give an example in the medical field, imagine a doctor and a nurse performing a surgery on a patient. In a direct statement, the following could be heard:
The doctor said, "Hand me the scalpel."
The same thing in the form of an indirect statement would be:
The doctor told be to hand him the scalpel.
