So we have a question asking about "ellipses." Which is the plural of ellipsis. Except it's not.
The post itself is kind of a non-sequitur, because the poster used the ellipsis tag and the plural that goes along with it, but appears to have meant Ellipsis the grammatical construct. OP has since removed the tag.
But then...why do we have this tag? I double checked. It has Usage guidance:
Just three little dots...
The longer description is:
An ellipsis is three dots or periods (...) used to indicate a pause, a speaker trailing off, or quoted material which has been cut out. When using an ellipsis at the end of a sentence, write it as four dots. Word processing software may replace three individual dots with a single ellipsis character.
Is there a story behind this? It was created in 2015 and has 6 questions (3 of which also tag punctuation).
Should we make it a synonym of punctuation which has 103 questions? As far as I can tell, there are no other tags for specific punctuation marks (aside from quotes but that's about more than the actual quote marks).
