The narrator of a work of fiction is the person (sometimes even animal or object) who tells the story. ‘Point of view’ POV) is the perspective from which the narrator (or ‘viewpoint character’) speaks.
In other words, from Neil Gaiman's quote - whose dream is this?
The first-person narrator recounts a personal narrative using the pronoun ‘I’. This narrator can be a main character in the story or a less involved observer. The inner worlds and thoughts of characters other than the narrator can only be revealed through what the narrator knows and chooses to tell the reader. Example: The title character and narrator of Charlotte Bronte’s Jane Ayre.
This less common type of narrator uses the second –person pronoun, ‘you’. This is a common device of ‘choose your own adventure books. Example: The narrator in If on a Winter’s Night a traveler, by Itralo Calvino. In this book, the reader is addressed as ‘you’, a character who sits down to read Calvino’s latest book and finds missing pages, leading the reader/protagonist on a quest to find the rest of the unfinished novel.
Limited Third Person
This narrator is similar to the first person narrator in that only what the narrator perceives and knows is available to the reader. The difference is that ‘he or ‘she’ is used rather than ‘I’. Other characters’ feelings and beliefs are only available through the narrator’s impressions or understanding and these may be limited or biased. Example: Most of J.K. Rowlings’s Harry Potter series (Rowling departs from the limited third person occasionally.)
This type of narrator has access to multiple characters’ thoughts and feelings and can describe them all within the course of a single book or even chapter. This is one of the more complex types of narrator. Example: The narrator of Louis May Alcott’s Little Women, who cycles through individual family members’ thoughts and feelings freely.
This name distinguishes a narrator whose credibility is suspect, unlike a reliable narrator. The narrator might be unreliable because he is willfully deceitful, but narrators can also be unreliable due to basing their stories on false information or assumptions. In this way the author exploits the obvious pitfalls of having an individual’s limited perspective. Example: The butler Stevens in Kazuo Ishiguro’s The Remains of the Day.
This type of narrator tells the events of the story in either the first or third person, but does not feature as one of the major characters in the course of events. Another term for this narrator could be ‘the witness’. The narrator is similar to the omniscient narrator in this respect, but only has the limited knowledge and perspective on an individual. Example: Nick Carraway in F. Scott Fitzgerald’s’ The Great Gatsby
