Use Incidental In A Sentence | Clear, Natural Examples

You’ve seen incidental in contracts, essays, novels, and travel receipts. It’s one of those words that sounds formal, yet it’s easy to use once you know what it’s doing in the sentence. Most of the time, it points to something that’s along for the ride: not the main thing, not the headline, just something attached to it.

This article shows what incidental means in plain terms, the sentence patterns that sound natural, and lots of ready-to-borrow sample lines for school and everyday writing.

What Incidental Means In Plain English

In everyday writing, incidental usually carries one of these ideas:

• Minor or secondary: Something that matters less than the main subject.
• Connected as a side effect: Something that comes along with another action or event.
• Extra costs: Small added charges that come with a bigger purchase or plan.

Dictionaries describe this “minor/secondary” sense clearly. You can check the Merriam-Webster definition of incidental when you want authoritative wording.

Incidental Vs. Accidental

Writers mix these up. Accidental points to something unintended that happened by mistake. Incidental points to something not central to the main matter. A spill can be accidental. A small fee on a bill can be incidental.

If you’re unsure, ask yourself a simple question: “Is this about a mistake?” If yes, accidental often fits. If it’s about priority and focus, incidental often fits.

How To Place Incidental In A Sentence

Incidental is most often an adjective. That means it describes a noun. You’ll usually place it right before the noun, or after a linking verb such as is, was, or seems.

Pattern 1: Incidental + Noun

This is the cleanest, most common pattern.

• The report includes incidental details that don’t change the conclusion.
• We budgeted for incidental expenses like parking and tips.
• She added incidental humor to keep the speech light.

Pattern 2: Be + Incidental

This works well when you’re judging relevance.

• Those dates are incidental to the main timeline.
• The color choice is incidental; the fit matters more.
• The side plot is incidental and can be cut without harm.

Pattern 3: Incidental To + Noun

This structure means “secondary compared with” or “not central to.” It’s useful in essays because it shows what you’re ranking as the main issue.

• The spelling errors are incidental to the argument, not the argument itself.
• Her job title is incidental to why she was invited.
• The noise is incidental to living downtown.

Pattern 4: Incidentally (The Adverb)

Incidentally means “in a side way” or “by the way.” It can also mean “not intentionally.” Use it when you’re adding a side note, not when you want to label something minor.

• Incidentally, the library closes early on Fridays.
• The photo captured him incidentally, not as the main subject.

Use Incidental In A Sentence In Common Writing Situations

The word sounds natural in school writing because it helps you rank ideas. It also works in practical contexts where you need to separate the main item from smaller attachments.

In Essays And Academic Writing

In essays, incidental helps you keep focus. It signals that you see a detail, yet you’re choosing not to treat it as the center of the argument.

• The author’s tone shifts, but that change is incidental to the chapter’s main claim.
• These statistics are incidental; the real issue is how the study was designed.
• Her personal story is incidental, used mainly to frame the topic.

In Business And Workplace Writing

In policies and emails, incidental often appears with costs, time, and tasks that come with a bigger project.

• Please submit receipts for incidental expenses within five business days.
• Printing is incidental to the training session and will be reimbursed.
• We expect incidental delays during the move, so plan extra time.

In Everyday Conversation

People do say incidental out loud, especially when they mean “not the main thing.” Keep the sentence simple and it won’t sound stiff.

• The rain was incidental; we still had a good time.
• That comment was incidental, so I didn’t take it personally.
• The extra fees were incidental, but they added up fast.

Sentence Templates That Make Incidental Sound Natural

If you want clean wording fast, start with a template and swap in your noun. These frames work in most contexts without sounding forced.

• [Noun] is incidental to [main idea].
• [Incidental noun] didn’t affect [main result].
• Aside from [main topic], there were incidental [details/costs/benefits].
• The [noun] was incidental, not the point of the discussion.
• We set aside money for incidental [expenses/costs].

Tip: Use a concrete noun right after incidental. “Incidental stuff” can work in casual speech, yet “incidental fees” or “incidental details” reads cleaner on the page.

Common Nouns That Pair Well With Incidental

Word pairings make writing feel fluent. These combinations show up often in real writing:

• incidental expenses
• incidental costs
• incidental details
• incidental findings
• incidental remarks
• incidental benefits
• incidental contact
• incidental music

Pick the pairing that matches your meaning. If you mean “side effect,” incidental benefit fits. If you mean “small charge,” incidental expense fits.

Meaning And Usage Map For Quick Choice

When you’re stuck, match what you want to say to the sentence shape that says it cleanly.

What You Mean	Best Pattern	Sample Sentence
Minor detail, not central	incidental + noun	The timeline includes incidental details that don’t change the main story.
Secondary compared with a main issue	incidental to + noun	That debate is incidental to the question we need to answer.
Small added charges	incidental expenses/costs	Bring extra cash for incidental expenses during the trip.
Side effect that comes along	incidental + noun	One incidental benefit of reading daily is a stronger vocabulary.
Something captured unintentionally	incidentally (adverb)	The microphone picked up the whisper incidentally.
Polite “by the way” insert	Incidentally, + clause	Incidentally, your folder is already shared with the class.
Not central, can be removed	be + incidental	The final paragraph is incidental and can be shortened.
Secondary task tied to a role	incidental + noun	Scheduling meetings is an incidental duty of the position.

Write Better Sentences With Incidental

Once you know the meaning, the next step is style: keep the sentence clear, and match the strength of the word to the setting. In a casual text, a single “incidental” can sound too formal. In an essay, it can be a strong tool for ranking ideas.

Pick The Right Level Of Formality

If the rest of your sentence is simple, incidental fits without sounding stiff.

• Good: The delay was incidental, so we moved on.
• Clunky: The incidental nature of the delay was perceived as noncentral by participants.

Be Clear About What Is Minor

Place the word near the noun it modifies. If readers have to guess what “incidental” refers to, the sentence loses punch.

• Clear: The contract lists incidental fees under “Other Charges.”
• Unclear: The contract lists fees that are incidental under “Other Charges.”

Use A Contrast When It Helps

A quick contrast can make the meaning snap into place. Keep it plain: “not the main issue,” “not the point,” “secondary,” “off to the side.”

• The photo’s background is incidental; the subject is the student at the podium.
• His accent is incidental, not a measure of his knowledge.

Common Mistakes And Clean Fixes

Most misuses happen for one of two reasons: the writer meant accidental, or the writer used incidental without showing what it’s secondary to.

Mistake 1: Using Incidental For A Mistake

If something happened by error, switch to accidental.

• Off: The glass broke incidental when I bumped the table.
• Better: The glass broke accidentally when I bumped the table.

Mistake 2: Forgetting The Comparison

When you write “incidental to,” name the main issue so the reader can see the ranking.

• Thin: That point is incidental to.
• Better: That point is incidental to the main claim about study habits.

Mistake 3: Overusing The Word

Use it when it earns its spot. If every detail is “incidental,” the reader stops believing you.

• Overdone: The intro, the examples, and the conclusion are incidental.
• Better: The intro is brief; the examples carry the message.

Goal	What To Avoid	Try This Instead
Show something is minor	Incidental without a noun	Use “incidental details/costs/remarks”
Rank two ideas	Leaving out the main issue	“Incidental to the main argument about…”
Describe a mistake	Using incidental	Use “accidental”
Add a side note	Using incidental (adjective)	Use “Incidentally,” as a lead-in
Keep tone natural	Heavy abstract nouns	Short clauses with concrete nouns

Practice Prompts You Can Use Right Now

Try these mini-prompts when you want to lock in the word. Write one sentence per prompt. Then read it aloud. If it sounds stiff, shorten the sentence and keep the noun concrete.

• Write about a class rule and mention an incidental detail that didn’t change the outcome.
• Write about a trip budget and list two incidental expenses.
• Write about a debate and show that one argument was incidental to the main issue.
• Write about a photo and explain what was incidental in the background.
• Write a note that starts with “Incidentally,” and add one useful side update.
