Dear Wanna Geddit Rite…
The choice of em-dash (—, which is the length of the letter “m” in the whatever font you’re using) versus ellipses ( . . . ) at the end of a sentence can be confusing. In a nutshell:
EM-DASH: Use for an interruption or a similarly abrupt cut-off. It can feel startling, even rude or cruel, as it chops a statement mid-sentence: “I wish I—” There’s drama in this punctuation choice. Used too often, it can overwhelm readers.
ELLIPSES: Use when a thought or sentence trails off gently into the sunset, “I wish I . . . ” If you’ve got a full sentence before the trail-off, insert sentence-ending punctuation right up against the last word of the sentence: “I wish I could dance. . . .”
I admit to being an em-dashaholic. I love the drama of that simple line. To cope with my obsession, I’ve learned to let the em-dashes fly in early drafts, then I strip them out in late revision. I’m aim to entertain readers, not overwhelm them.
