What does it mean to be active? Often, when people think of “active,” they imagine themselves doing some sort of physical activity, like exercise. Perhaps you think of someone dancing, running, or even doing chores around the house. In writing, an active voice has a similar meaning as well. A sentence that uses active voice is one where the subject is the one performing the action, or the verb. In contrast, passive voice works the opposite way, with the subject being acted on by the verb. To write effectively, you should avoid passive voice because it takes away from your overall clarity of ideas. Instead, use active voice to ensure that your ideas are written in the most concise way.
