when do you use four periods in an ellipsis
Ellipsis Whether an ellipsis at the end of a sentence needs a fourth dot to finish the sentence is a matter of debate; Chicago advises it,[4] as does the Publication Manual of the American Psychological Association (APA style),[5], while some other style guides do not;[citation needed] the Merriam-Webster Dictionary and related works treat this style as optional, saying that it "may" be used.[6] More commonly, a normal full stop (period) terminates the sentence, then a separate three-dot ellipsis is used to indicate one or more subsequent elided sentences before continuing a longer quotation. Business Insider magazine suggests this style,[7] and it is also used in many academic journals. Even the Associated Press Stylebook[8] – notably hostile to punctuation that journalists may consider optional and removable to save newsprint column width – favors this approach. It is consistent in intent if not exact form with the agreement among those in favor of a fused four-dot ellipsis that the first of them is a full stop terminating the sentence and the other three are the ellipsis.
