This means:
* Third-person: The narrator refers to characters using "he," "she," or "they."
* Limited: The narrator knows the thoughts and feelings of only one character (likely the one observing the lottery).
* Omniscient: The narrator has access to information and understanding of events that the characters may not be aware of.
The story's anonymity helps contribute to its unsettling atmosphere and the feeling that the traditions of the town are mysterious and out of reach for the reader.
