What defines active voice in sentence structure?

Active voice in sentence structure is defined by the subject performing the action of the verb. This construction is direct and clear, as it allows the reader to easily identify who is doing what in the sentence. For example, in the sentence "The manager approved the budget," "the manager" is the subject actively carrying out the action of approving. This clarity enhances the overall effectiveness and engagement of the writing, making it more dynamic and easier for readers to follow.

Other constructions, such as passive voice, would have the subject receiving the action instead of performing it, which can sometimes lead to ambiguity or a lack of directness. Active voice conveys a sense of immediacy and directness, contributing to more vigorous and compelling writing. The form of the verb, such as being in past tense, or the placement of the object in relation to the subject does not define active voice. Instead, it is specifically about the subject's role in executing the action expressed by the verb.
