Active Voice: This is a grammatical structure where the subject of the sentence performs the action. In an active voice sentence, the focus is on who is doing the action. For example, "The dog chased the ball" highlights that the dog (the subject) is actively performing the action of chasing.
Passive Voice: This is a grammatical structure where the subject of the sentence receives the action rather than performing it. In a passive voice sentence, the focus shifts to the action itself or the recipient of the action, often making the doer less important or even unknown. For example, "The ball was chased by the dog" emphasizes the ball being chased rather than who is doing the chasing.
