Ellipses is a three-dot placeholder for omitted text or ideas.
Ellipses … those three dots to the left.
Rule 1. Three dots. Always. Only. No more. No less.
Rule 2. Insert a space before and after the ellipses.
Ellipses and a period, those four dots to the right ….
Rule 1. Three dots. Always. Except at the end of a sentence.
Rule 2. Insert a space between the last word and the ellipses.
Rule 3. Do not insert a space between the ellipses and a period.
Easiest fix: use the full quote, complete the thought, or itemize the list instead of using the ellipses as a placeholder.
