3 dots is formally correct to skip parts of a sentence or paragraph when quoting another party for an essay
Eg. "The mountain had crystals in it...above the clouds was a rainbow." Because you don't need to write the whole paragraph you're trying to give evidence.
2 dots to me is an informal and cute way of implying there is something else to say except philosophically you don't need to say it at that moment so it's more of a short-cut and yes 2 dots is quicker that 3 since 3 means something else formally any-way. 2 dots is a short 3 And us developing its own meaning. Graphically it's different and to me it reflects how the person is writing. Définitely our writing, the way we communicate in our lives and the way we communicate is changing.
So I agree with how 2 dots is a quick shorten mid sentence to cut it all short when you actually don't know what's next or want to keep it open. It's more poetic and a modern thing with social media, iPhones and emails. When you want to be brief and are implying something else. I think it's grammatical implication and meaning is developing.
I use 4 dots for a similar poetic meaning like when you are ending something with an indefinite thought at the end, more of an artistic label
Eg. With love.... Sometimes 8 for lots of love........x
So shortened 2 dots is like a short pause and think when there's no time to get further into it and its left open ended. 3 dots is a formal gap with a meaning of omission in formal writing or meaning you have left out what us to come. 4 dots is an ending, provoking more thought. 3 dots you can also use correctly to change topic...it's the most formally correct if youre writing properly.
From what Ive experienced and studied in language, literacy, grammatical and literature.
I think there is a new place for 2 dots and agree some people will misuse it for the formally correct 3 dots. 2 dots I would use for more of a thought or conversation informally. When Im not committing to make a formal '...' statement. Like if texting with a friend while shopping e.g. "Do you like the pink dress?" "It's alright.. Maybe lets go to Bondi?" So this means Im still deciding, part way through and unsure. I could more formally write "It's alright...maybe lets go to Bondi?" To me this is more définitive. It's 2 différent ways of texting/writing/communicating and a différent style of writing.
We use 2 dots knowing 3 dors us correct so, it does havé a meaning and place whether it not it is misused!
I was editing a surf photography website and 2 dots were put in as opposed to 3 and it was in association to a dream and love it was so poetic, and spoke to me, I couldn't change it.
Josie thanks! That helps!
