Common Mistakes with the Verb ‘run’
The verb run is one of the most frequently misused irregular verbs in English. The core problem is that its past tense form is ran, and its past participle form is run—but many learners (and even native speakers) confuse these two forms, especially in perfect tenses and passive constructions. This guide explains exactly where the mistakes happen, gives you clear rules, and provides practical examples so you can use run correctly in writing, conversation, and email.
Quick Answer: The Three Forms of ‘run’
- Base form: run (I run every morning.)
- Past tense: ran (She ran to the bus stop yesterday.)
- Past participle: run (They have run the marathon twice.)
The most common error is using ran where run is needed (e.g., “I have ran” instead of “I have run”) or using run for the simple past (e.g., “Yesterday I run” instead of “Yesterday I ran”).
Why This Verb Causes Confusion
Unlike regular verbs that add -ed for both past tense and past participle (e.g., walk → walked → walked), run changes its vowel in the past tense (ran) but returns to the base form for the past participle (run). This pattern is unique and easy to mix up, especially in spoken English where the difference can sound subtle.
In formal writing and professional emails, using the wrong form can make your English sound careless. In conversation, it may confuse the timeline of your story.
Comparison Table: Correct vs. Common Mistakes
| Tense / Structure | Correct Form | Common Mistake | Why It’s Wrong |
|---|---|---|---|
| Simple Past | I ran home. | I run home. | Past tense requires ran. |
| Present Perfect | She has run the report. | She has ran the report. | Past participle must be run. |
| Past Perfect | They had run out of time. | They had ran out of time. | Past participle must be run. |
| Passive Voice | The program was run by IT. | The program was ran by IT. | Passive uses past participle run. |
| Present Tense (3rd person) | He runs fast. | He run fast. | Subject-verb agreement requires runs. |
Natural Examples in Context
Everyday Conversation
- “I ran into Sarah at the grocery store.” (simple past, correct)
- “Have you run the dishwasher yet?” (present perfect, correct)
- “We ran the numbers, and they look good.” (simple past, correct)
- “The battery has run out.” (present perfect, correct)
Email and Professional Writing
- “I have run the analysis and attached the results.” (present perfect, formal)
- “The test was run twice to confirm accuracy.” (passive voice, formal)
- “We ran the campaign last quarter.” (simple past, neutral)
- “Please ensure the script has been run before the meeting.” (passive perfect, formal)
Informal vs. Formal Nuance
In casual speech, you might hear “I runned” from children, but adults should avoid it. In formal writing, always double-check that you haven’t used ran after have, has, had, or in passive constructions. For example, “The system has run smoothly” is correct; “The system has ran smoothly” is a common error in business emails.
Common Mistakes and How to Fix Them
Mistake 1: Using ‘ran’ after ‘have’, ‘has’, or ‘had’
Incorrect: “I have ran three miles today.”
Correct: “I have run three miles today.”
Why: The present perfect always uses the past participle (run), not the past tense (ran).
Mistake 2: Using ‘run’ for the simple past
Incorrect: “Yesterday, I run to the station.”
Correct: “Yesterday, I ran to the station.”
Why: The simple past requires the past tense form (ran).
Mistake 3: Confusing ‘run’ with ‘ran’ in passive voice
Incorrect: “The event was ran by volunteers.”
Correct: “The event was run by volunteers.”
Why: Passive voice uses the past participle (run).
Mistake 4: Forgetting the third-person ‘s’ in present tense
Incorrect: “He run a small business.”
Correct: “He runs a small business.”
Why: Third-person singular subjects require runs in the present tense.
Better Alternatives and When to Use Them
Sometimes run is overused. Here are more precise verbs depending on context:
- Operate (formal): “She operates the machinery.” Better than “She runs the machinery” in technical writing.
- Manage (professional): “He manages the department.” More specific than “He runs the department.”
- Dash (informal, quick movement): “I dashed to the store.” More vivid than “I ran to the store.”
- Function (technical): “The software functions correctly.” More precise than “The software runs correctly.”
Use run when you mean physical movement, operation of a system, or a general process. Choose alternatives when you need a more formal or specific tone.

Frequently Asked Questions
1. Is it “I have run” or “I have ran”?
The correct form is I have run. Ran is only used for the simple past tense (e.g., “I ran yesterday”). After have, has, or had, you must use the past participle run.
2. Can I use “run” as a noun?
Yes. Run can be a noun meaning a period of operation, a race, or a series of events. For example: “We had a good run with the project.” The verb forms still follow the same rules.
3. What about “run” in the past perfect?
Use had run. Example: “By the time we arrived, the movie had already run for an hour.” Never use “had ran.”
4. Is “runned” ever correct?
No. Runned is non-standard and considered incorrect in all contexts. Always use ran for simple past and run as the past participle.
Final Tip for Real Writing
When you write an email or a report, read your sentences aloud. If you hear ran right after have, has, or had, change it to run. If you are describing a finished action in the past without a helper verb, use ran. This simple check will eliminate most of your errors with this tricky verb.
