Answer 1

In grammar, the relationship between the action/state of the verb and the subject is expressed in two forms of voice: Active voice and Passive voice.

Active form: In active sentences the subject is doing the action, and the object is receiving it.

{Thing doing it i.e. subject} + {verb} + {thing on which it is done i.e. object.}
