Ellipsis point .
Ellipsis . . .
Ellipses . . . . . . . . .
For examples I'm using POISON by Bridget Zinn (my favorite 2013 published read).
On the first page I opened to (90-91) I found 3 uses of ellipses.
1. Ellipses can also show hesitation
"The witch squinted at Kyra's midsection. 'Well . . . what a nice surprise: a spark.'" (I love this one because it also uses a colon *happy dance*)
Not in dialogue:
"It smelled like . . . herbs, fresh-picked, but with an undertone of something else, something powerful and scary."
2. Ellipses can show trailing off in dialogue (leaving something unsaid).
"'And finally . . .' Out came a flat glass disk." (no space between last ellipsis point and quotation marks)
3. Ellipsis show omission, such as to shorten a quotation.
"Kyra followed, considering her options. She had no idea how to unfreeze her upper body. . . . Possibly the witch would either have to lose interest or die before the spell would evaporate."
"She spied Fred . . . sitting at a rough-hewn table . . ."
Do you use ellipses in writing? Did Grammar Girl get it right? Have you read POISON?
