Answer:
Macbeth, a Scottish general, is known for his fearless character on the battlefield that brings him great admiration from the king.
Step-by-step explanation:
An Appositive is described as a noun or a noun phrase(explanatory equivalent) that immediately follows another to define, identify, or describe the former.
In the above sentence, the appositive 'a Scottish general' is the noun phrase that is describing the previous noun 'Macbeth.' It exemplifies the construction in which the one noun phrase('a Scottish general') is placed with another('Macbeth') as an explanatory equivalent. Both of them, however, has the same syntactic function in the sentence. Appositives are non-restrictive in nature as removing it does not affect the meaning of the sentence.
