Profanity is one of those tools writers either lean on too hard or avoid like it’s radioactive. But swear words aren’t automatically “bad writing” or “edgy writing.” They’re just words and like any other words, they need to earn their place on the page.

If you’re deciding whether to drop an f-bomb (or like in some of my stories, fifty), here’s some guidelines I go by:

Every word should serve character or plot

A useful gut-check: what does this profanity do?

• Does it reveal a character’s temperament, background, stress level, or worldview?
• Does it intensify a moment that matters to the plot?
• Does it sharpen the rhythm of dialogue in a way that fits the scene?

If the answer is “it just sounds cool” or “it makes this feel more adult,” it’s probably filler. Profanity is strongest when it functions as characterization.

Try this: Remove the swear word. If the line loses meaning, tone, or character truth, you may need it. If nothing changes, omit it.

Profanity comes with a real risk of offending some readers

I do think this is less of an issue than it was say fifty years ago, but it is something to keep in mind.The key is to choose intentionally and ask yourself:

• Who is my target audience for this story?
• What’s the tone I’m going for here (cozy mystery vs. grim thriller, for example)?
• Am I okay with losing some readers because of this?

One thing profanity is good at is a quick way to signal genre and voice. It can also break immersion for readers who don’t like it.

Profanity should be true to the character, not the author

The best profanity usually feels inevitable. In other words the character couldn’t have said anything else.

A few examples of true to character uses:

• A character swears when they’re scared, cornered, or losing control.
• A character uses profanity casually because it’s part of their everyday speech.
• A character never swears… until the moment it finally slips, and that tells us something about what is going on.

On the flip side, try to avoid:

• A character who suddenly starts cursing because the author wants the scene to feel “more intense.”
• Everyone in the cast swears in the same way (same words, same rhythm), which usually makes it feel like it’s the writer’s voice coming out of all of them.

Can you identify who’s speaking if you remove the dialogue tags? If swearing makes the voices blur together, then it’s really not adding anything of value.

Profanity should also be thought of as a natural byproduct of:

• real emotion
• real conflict
• real character choices

If the scene is already powerful, profanity can add some heat, but if the scene isn’t working to begin with, adding profanity won’t fix it.

The one F-word check. I see this in stories a lot more than you would expect; a story has little to no swearing then, out of nowhere, a character drops the F-bomb.

If you use the F word only once in the entire story, ask yourself whether you really need it. There are two reasons I can think of why, as Ralphie would say, the Queen mother of dirty words would only appear once:

1. It’s true to the situation.
   Maybe it lands at the exact right emotional peak, and the rarity makes it hit harder. Sure go ahead and keep it it in.
2. Shock value.
   If the profanity exists mainly to jolt the reader, it can feel cheap and manipulative. Readers can can tell when the author is yanking at the steering wheel. It reminds me of a creative writing teacher I had who would always talk about the author “Showing their hand.” His point was that only in rare cases is that a good thing.

Before you submit, ask these questions:

• Does this word reveal character or move the plot?
• Would this character really say it, right here, right now?
• Is it doing more than just trying to sound edgy?
• Am I okay with the readers I might lose?
• If this is my only F word, is it really needed?

If you can answer “yes” to those, you’re using language with intent.

The goal is to write in a way that is true to the characters and true to the story. Remember a great way to to test is by taking out the “bad words” to see how it affects the story. If, after that you still can’t decide… well, sometimes you just have to say “Fuck it.”
