Most writers mean “at risk of,” not “at a risk of,” because the article “a” usually makes the phrase sound unidiomatic in English.
You’ve seen it in essays, emails, captions, and even headlines: “at a risk of.” It looks close enough to pass at a glance, yet it often reads off to native speakers. If you’re learning English, or you write for school or work, this tiny choice can quietly lower the clarity of your sentence.
This article gives you a clean rule you can trust, plus the small set of cases where “a risk” does belong. You’ll get patterns you can reuse, quick rewrites, and a checklist you can run in seconds before you hit publish.
What “At Risk Of” Means In Plain English
“At risk of” means “in danger of” something happening. The danger can be physical, financial, academic, technical, or anything else that can go wrong.
You’ll usually see it followed by a noun or a gerund (-ing form):
- Noun: “The files are at risk of loss.”
- Gerund: “The files are at risk of being lost.”
In many sentences, “at risk of” works like a compact warning label. It tells the reader, fast, what bad outcome is on the table.
At A Risk Of In Writing: What To Use Instead
Most of the time, replace “at a risk of” with “at risk of.” Drop the “a.” The sentence will sound more natural and more direct.
Try these side-by-side fixes:
- Wrong: “Students are at a risk of failing the course.”
- Right: “Students are at risk of failing the course.”
- Wrong: “The device is at a risk of overheating.”
- Right: “The device is at risk of overheating.”
Why does the “a” cause trouble? Because “at risk” is a set phrase in modern English. It behaves like a fixed unit, not like “at + a + noun” in the usual way.
When “Risk” Acts Like A Label
In “at risk,” the word “risk” acts like a state: the person or thing is in the state of being vulnerable to harm or failure. That’s why you’ll also see “at-risk” used as an adjective before a noun, like “at-risk students.” Major learner dictionaries treat “at-risk” as a standard form. Cambridge Dictionary’s entry for “at-risk” shows this meaning and common usage.
Once you spot “at risk” as a label, the fix gets easy: labels usually don’t take “a” inside the label itself. You wouldn’t say “in a danger of” either; you’d say “in danger of.”
Two Fast Tests That Catch The Error
If you’re unsure, run either test:
- Swap test: Replace the whole phrase with “in danger of.” If “in a danger of” sounds wrong, “at a risk of” is likely wrong too.
- Delete test: Remove the “a” and read the sentence out loud. If it gets smoother, keep it removed.
When “A Risk” Is Correct
“A risk” is fine when you mean one specific risk among many, or when you’re describing risk as a countable thing. In that case, “risk” is not a label. It’s a noun you can point to, measure, compare, or rank.
Here are common patterns where “a risk” belongs:
- “There is a risk of …” “There is a risk of delays.”
- “Pose a risk” “Loose cables pose a risk to runners.”
- “Carry a risk” “This plan carries a risk of errors.”
- “Create a risk” “Sharing passwords creates a risk of account takeover.”
So the core idea is simple: use “at risk of” for a state, and use “a risk” when you’re naming one countable danger.
Common Sentence Patterns You Can Copy
Once you know the handful of normal patterns, you can write clean sentences without stopping to second-guess. Mix and match these like building blocks.
Pattern 1: “Be At Risk Of + Noun”
This pattern is compact and works well in academic writing:
- “Coastal homes are at risk of flooding.”
- “The records are at risk of deletion.”
- “New users are at risk of confusion without clear labels.”
Pattern 2: “Be At Risk Of + Gerund (-ing)”
Use this when the outcome is an action or process:
- “The battery is at risk of failing early.”
- “The team is at risk of missing the deadline.”
- “The plant is at risk of dying in dry soil.”
Pattern 3: “Be At Risk Of Being + Past Participle”
This is a clean passive form when you don’t want to name who causes the harm:
- “The files are at risk of being lost.”
- “The item is at risk of being damaged in transit.”
- “The account is at risk of being locked.”
Pattern 4: “Run The Risk Of + Gerund”
This form adds agency. It suggests someone chooses an action that could backfire:
- “If you skip the citation, you run the risk of losing marks.”
- “If you share the link publicly, you run the risk of spam.”
Usage Notes That Trip Learners Up
Most mistakes come from mixing two correct ideas into one incorrect phrase. You may know “there is a risk of” and “at risk of,” then merge them into “at a risk of.” That blend is the source of the problem.
Another trap is trying to make every noun phrase match the pattern “at a + noun.” That pattern exists, like “at a disadvantage” or “at a loss.” Yet “at risk” is its own fixed phrase, so it doesn’t follow the same rule.
One more note: “at-risk” with a hyphen is normal before a noun (at-risk students, at-risk areas). Without the hyphen, it’s normal after a linking verb (students are at risk). Many dictionaries show both uses, including Oxford’s learner entries for “at-risk.” Oxford Learner’s Dictionaries: “at-risk” is a handy reference if you want to double-check the form.
Choose The Right Phrase For The Tone You Want
Different forms can carry different tone. If you’re writing an assignment, a report, or a formal email, you may want a neutral tone. If you’re writing instructions, you may want a direct warning tone.
Here’s how to pick:
- Neutral, factual: “The system is at risk of failure.”
- Personal, action-focused: “You run the risk of losing your work if you don’t save.”
- Formal, report style: “There is a risk of delays due to maintenance.”
- Clear cause-and-effect: “Loose wiring can create a risk of fire.”
Pick the form that matches your goal, then keep your sentence tight. If you can remove extra words without losing meaning, do it.
Rewrite Examples From Real-World Writing
Let’s fix a few lines in the style you’ll see in essays and workplace writing. Watch the pattern: remove “a” after “at,” or change the structure to “there is a risk of.”
Academic Writing
- Before: “Children are at a risk of falling behind in reading.”
- After: “Children are at risk of falling behind in reading.”
Work Emails
- Before: “We are at a risk of missing the delivery window.”
- After: “We are at risk of missing the delivery window.”
Tech Notes
- Before: “The server is at a risk of going down during peak hours.”
- After: “The server is at risk of going down during peak hours.”
Safer Alternative When You Want To Sound Formal
- Before: “Users are at a risk of data loss.”
- After: “There is a risk of data loss for users.”
Both “after” lines are fine. Choose based on the flow of the paragraph and what you want to stress: the state (“at risk”) or the existence of the hazard (“there is a risk”).
Table: Correct Forms, What They Mean, And When To Use Them
The table below is a quick reference you can keep open while you edit. It shows the forms that sound natural in modern English, plus a note on what each form signals.
| Form | Use When | Example |
|---|---|---|
| At risk of + noun | You’re naming an outcome | “The account is at risk of closure.” |
| At risk of + gerund | You’re naming an action outcome | “The team is at risk of losing points.” |
| At risk of being + past participle | You want a passive form | “The file is at risk of being deleted.” |
| At-risk + noun | You need an adjective before a noun | “At-risk students need clear study plans.” |
| There is a risk of + noun/gerund | You want a formal report tone | “There is a risk of delays.” |
| Run the risk of + gerund | You’re warning about a choice | “You run the risk of failing if you skip practice.” |
| Pose/carry/create a risk | You’re naming a cause of danger | “Loose cords pose a risk of trips.” |
| Put (someone/something) at risk | You’re pointing to a harmful action | “Sharing passwords puts accounts at risk.” |
How To Edit Your Draft In Under One Minute
Here’s a fast editing routine that works for essays, blog posts, and captions. You don’t need grammar jargon. You just need to spot the pattern and swap it.
Step 1: Search For “At A Risk”
Use your editor’s find tool. If you see “at a risk of,” change it to “at risk of” in nearly all cases.
Step 2: Check The Word After “Of”
If the next word is a noun (loss, failure, delays), you’re fine. If the next word ends in -ing (failing, losing, breaking), you’re fine. If the next words start with “being,” you’re fine.
Step 3: Decide If You Want A Report Tone
If your sentence sounds too blunt for your setting, shift to “there is a risk of.” This keeps the meaning but softens the directness.
Step 4: Read One Sentence Before And After
“At risk” can repeat if you use it many times in a row. If you see three in one paragraph, keep one, then swap the others to “there is a risk of” or “run the risk of” where it fits.
Table: Clean Rewrites You Can Paste
Use these rewrites as templates. Swap in your own nouns and verbs, and keep the structure the same.
| Draft Line | Better Line | Why It Reads Better |
|---|---|---|
| “We are at a risk of missing the deadline.” | “We are at risk of missing the deadline.” | Uses the standard fixed phrase. |
| “The laptop is at a risk of overheating.” | “The laptop is at risk of overheating.” | Keeps the warning tight and natural. |
| “Users are at a risk of data loss.” | “There is a risk of data loss for users.” | Fits a report tone without sounding stiff. |
| “She is at a risk of failing the exam.” | “She is at risk of failing the exam.” | Removes an unneeded article. |
| “The files are at a risk of being deleted.” | “The files are at risk of being deleted.” | Fixes the phrase while keeping the passive form. |
| “We’re at a risk of losing trust.” | “We run the risk of losing trust.” | Adds agency when the risk comes from a choice. |
Mini Checklist For Exams, Essays, And Blog Posts

- If you want a formal tone, use “there is a risk of.”
- If the sentence warns about an action, use “run the risk of.”
- If “at risk” repeats too often, keep one and vary the rest with the patterns above.
- Read the sentence out loud once. If it sounds smooth, you’re done.
That’s it. One small fix, and your writing instantly sounds more natural.
