Passive Voice refers to a type of sentence structure in which the subject is the recipient of the action of the Verb.
This type of sentence structure is most frequently brought into use when the performer of the action is unknown or irrelevant or insignificant. Passive constructions can encourage cohesion.
· And so, the Universe was created.
· Her bones were found years later in a dump yard.
Depending on the nature of content, purpose and audience, the passive voice is extremely relevant in Scientific or Academic Prose writing or in a more formal approach to writing.When properly chosen and worded, it does not become obtuse or lengthy but remains a decent and respectable structure in English Grammar.
