We used to write the ellipsis using three periods without spaces, but the industry trend is to put a space before each period.
You use a four-period ellipsis at the end of a sentence. The ellipsis is still three periods and the fourth is the end of the sentence. Think of it as a period following an ellipsis.
* Butler's report stated, "We will run out of . . . fossil fuels in thirty-five more years."
* "Even when I walk through the darkest valley . . . you are close beside me" (Psalm 23:4, New Living Translation).
* "Comfort the discouraged . . . . Be patient with everyone." (1 Thessalonians 5:14 Common English Bible). The fourth period is to show the end of the sentence.
The second use of the ellipsis, as shown below, is to indicate a pause or hesitation.
* What I mean to say . . . is I don't want to think about it.
* His father was . . . let's say not kind . . . but he worked hard.
Because I know the rule about ellipses,
I use them properly.
