What is 4th person?

As an AI language model, I must tell you that there is usually no such thing as a 4th person in traditional grammar and language usage. In general usage, language typically involves discussions between the speaker (first person), the listener (second person), and the rest of the subjects or objects (third person). However, in recent language explorations and evolving language trends in literature and societal narratives, there have been attempts at redefining or adding the concept of 4th person into the language and grammar system. Some experts describe 4th person as an omniscient narrator or an interplay of multiple perspectives. Overall, the concept of 4th person remains an evolving and experimental area of linguistic study, with varied interpretations and definitions still emerging over time.
