I try to not put them at the end of the sentence, I’m not so old I don’t get the implication of that! It’s in the middle of the sentence as a break!
Or sometimes as a literary device to indicate an amount of time has passed.
Using ellipses in the middle of a sentence is considered very rude.
Have you ever met someone who pauses in the middle of a sentence… just to fuck with you by injecting pointless suspense? Well, believe it or not… this is what ellipses communicate in written English. You’re building a lot of dramatic suspense and slowing down the pace at which people read your messages… and if you don’t pay it off… you seem like an asshole.
I don’t watch much reality television, but those shows like to inject massive pauses right before the judge reveals whether the chef made a good meal… just so they’ll gasp more and cry with relief and the audience will stay invested. But I hate it! It’s really annoying! And it’s how some people type.
The implication is that you know the next part of the sentence but keep it unwritten. The best exemple is when making a list, a, b c …
Sometimes it’s even just a indicator there’s gonna be a next part, like the “We need to talk…”
Although the more degenerate use is to imply the “you know what i mean/imply”, a bit like the english innit in some sens.
