Ellipsis: Examples and Meaning – The Grammar Guide (prowritingaid.com) – click link for full article
I use Ellipsises, Ellipsi – oh, the article provides the plural – Ellipses a lot in my writing. Originally introduced to it for formal writing when words are dropped from a quote, I’ve embraced it for fiction writing when a character drifts off in what they want to say … and in informal writing for a change of thought that is sideways related to what I’m saying. Close enough that a period isn’t appropriate, but far enough away that a comma doesn’t work either.
