First person: Talking about oneself. I, me.
Second person: talking about the listener. you, your.
Third person: talking about someone who is not the speaker or listener. He/she/it/they
Fourth person: Talking about total bullshit.
In this context, "Chat" is second-person plural, used by streamers to address the portion of their audience able to respond in the text chat that always accompanies these things. It does contrast with how a radio personality might address "listeners" because radio listeners don't usually have a method to respond in real time, so it's usually a rhetorical question; a streamer addressing the chat is asking for a response.
i saw someone argue for chat being a 4th person pronoun because it breaks the 4th wall usually seen in mass broadcast media, there's still a degree of interaction that isn't there on live TV, so "chat is this real" prompts a direct response from a unified mass of people, there's a conversation happening through the 4th wall basically
I might buy the 4th person as "someone outside your continuum or reality," but I've yet to see a language construct specifically for that. Fictional characters invariably use second or third person to refer to the audience outside their world.
Streamers talking with their chat audience aren't fictional or otherworldly though. I don't see a linguistic difference between a streamer asking the chat what game he should play next, to Bob Saget saying "Home viewers, if you have a funny home video, send the tape to the address on your screen for a chance at appearing on our show!" It's a communique addressing a large scattered audience through audio/video telephony soliciting a reply. The only real difference is round-trip latency.
While I think the phenomenon of live streaming and their audiences is interesting and presents a fairly new experience, I don't know if it's "we're inventing new pronoun tenses over here."
Seems like the same thing to me. I think the person saying it's the first of its kind is wrong, but it would still be equally bizarre if people were addressing their "listeners" in normal conversation.
It speaks to a person that isn't physically present and just an observer. "You" typically addresses someone directly, but can be used to break the 4th wall and talk to observers. "Chat" is exclusively for breaking the 4th wall.
Nah, "chat" is talking to a specific, present group of people, and is used in lieu of writing a text chat. It's not like a film actor speaking to the audience, who has no way of responding. Even so, any terms used in breaking the fourth wall would still be second person, ability to respond and presence aren't a requirement here (e.g. you'd use "you" in letters, and the reader is absolutely not present).
There are languages with a 4th person pronoun. The 3rd person is kind of the main character and the 4th someone else. That helps to disambiguate sentences like "The criminal shot the cop and drove away on his (own or the cop's) bike".
Or the "gay fanfiction problem": "He looked at him and lay his hands on his lap". Is it a happy ending or a sad one? That's one theory why gender in pronouns is so resilient: more often than not, the gendered pronoun can disambiguate which person is talked about. It doesn't always work, a 3rd/4rd person distinction is superior.
You can have an alternate third person pronoun I suppose in order to distinguish two third person individuals, but that doesn't mean there's a fourth person pronoun. The general definition is:
first person - the speaker
second person - the audience, whether present or not present
third person - someone or something other than the audience
So things like "chat" and "breaking the fourth wall" are second person pronouns. There is no fourth person pronoun, because anything other than first and second is covered under third person.
