a piece of literature contains a speaker who is speaking either in the first person, telling things from his or her own perspective, or in the third person, telling things from the perspective of an onlooker
if the speaker knows everything including the actions, motives, and thoughts of all the characters, the speaker is referred to as omniscient (all-knowing)
if the speaker is unable to know what is in any character’s mind but his or her own, this is called limited omniscience
