Answer:
I don't know what sentance you're talking about but the answer would be a pronoun
Explanation:
1st POV would be the use of "I", "My",
ex: I went to the store
2nd POV: It's rare but it uses "You" as if you are in the story
ex: You went to say hi to them
3rd person: Uses pronouns "She/Her/Him/They/Them"
ex: They went to pet the dog
Hopefully this helps!
