ساختار معلوم و مجهول
In writing, sentences are considered to be of “active” or “passive” construction (“voice”) depending on where the emphasis is placed. If the emphasis is placed on the subject, the sentence is considered active, but if emphasis is placed on the object of the action, the sentence is passive. Wikipedia’s passive voice definition states, “The passive voice is a grammatical construction (a ‘voice’) in which the subject of a sentence or clause denotes the recipient of the action (the patient) rather than the performer (the agent).
