Step-by-step explanation:
well im not sure if I quite understand the question but ill just explain all the povs. hope this helps!!
first person pov: the narrator tells the story from their own point of view- examples are when they use words like I and my-
second person pov: the narrator is telling "you" your story- its often used for giving instructions
Third person pov: the narrator tells the story about someone else (there are 3 types of third person that ill explain):
objective third person: it only describes what happens- no thoughts, feelings, or extra input
limited third person: it describes the feelings/emotions of 1 character- it may describe the past or present of that character
omniscient third person: the narrator is an all-knowing figure (when I say this i mean they know absolutely everything including the thoughts and emotions of all the characters) they also know the past, present, and future of everything)
now for how the pov affects how the story events are described-
"Point of view is important in a story because it helps the reader understand characters' feelings and actions. Each character will have his or her own perspective, so whoever is telling the story will impact the reader's opinion of other characters and events"
