So I'm trying to write this piece of dialogue, and I want to show the way the speaker emphasizes each separate word. The line of dialogue: "No matter what delusions you might have about it, you don't belong here." (The issue only applies to the last four words.) You might be familiar with the way many people on the internet do this. They. Place. A. Full. Stop. Behind. Every. Word. It's okay on social media and such, but I find it (no offense) tacky in a novel. It has the desired effect, but I'm looking for something more 'formal'. I hope to hear your suggestions.
I've seen the full stop in novels, and it works ok. Another easy way is to simply note in a beat or dialogue tag that the speaker is emphasizing every word.
I can see using the full stops, honestly, but if that's not your thing, I'd do something like: Using the italics should indicate that you only mean those words. (Basically, what @Steerpike said.)
I would go for something visual like: 'No matter what delusions you might have about it.' He turned and squared up to her. 'You don't belong here.' Each word was hurled at her, all finding their mark. Or some other variation. Probably a lot will come down to style as to which is the best fit for you.
I've seen the full stops in novels and I think if it is used rarely and carefully (only 2-4words to set the right tone), then it is great. The periods give an added effect that italics do not for me. It's not just a strong emphasis. It's denoting a distinct pause. I've seen one of my authors use it on one occasion and she has over 10 books in her series. Was perfectly fine from memory, and I love her voice because she is expressive. Her books would also appeal to a younger audience I think. I don't think it is tacky generally. It's no different than people using dashes to create an interruption in dialogue. Where similarly, if used too much, is a distraction and appears tacky.
Thank you so much for all your replies. I didn't expect so many answers in less than 24 hours. Definitely a good first experience with this site. As for the question, I might still go with the full stops as some of you suggested or use italics and clarify the emphasis in a dialogue tag.
"No matter what delusions you might have," he said, and then slowed down to speak each word clearly, "you do not belong here." In particular, remove the elision from don't.
The full stop thing just looks weird to me and I can't help but read it robotically or skip over it the first couple times I read it. I don't think I ever really knew why a person put the full stops in until I read this thread (thanks for letting me know!). I much prefer italics. When something like that is in italics, I naturally read it the way you want it read: with every word having a meaning and being said with emphasis, but without my brain pausing and driving me crazy trying to put a sentence of words together while also trying to separate them. Would I stop reading a novel because of a full stop emphasis, or would it ruin the overall experience of the novel? Nope! I might go, "Um, okay, that was a little weird," but if it's not in there a lot, I'll deal with it and move on (if it's in there a lot and I'm really into the story, I'll be annoyed with the author but continue reading). Do whatever suits your style and tell the readers like me to like it or lump it--just don't go overboard. Edited to add ALL CAPS can have the same effect. Just don't put an exclamation point at the end, or the readers will think the person's just shouting.
