If you’ve ever paused mid-sentence wondering whether to say “has ran” or “has run”, you’re not alone. This is one of those tricky English grammar conundrums that even native speakers stumble over. The confusion comes from the fact that run is an irregular verb, meaning it doesn’t follow the predictable -ed pattern.
The difference between has ran and has run isn’t just about being a grammar perfectionist—it can change the clarity and correctness of your message.
In this guide, we’ll break down the rules, look at real-life examples, provide tables for easy reference, explore common mistakes, and give you practical tips to ensure you’ll never second-guess yourself again.
Understanding the Core Difference Between “Has Ran” and “Has Run”
The key lies in verb tense.
- “Run” is the past participle of the verb “to run.”
- “Ran” is the simple past tense of the verb “to run.”
When you use “has”, you’re forming the present perfect tense, which always requires a past participle, not the simple past.
✅ Correct: She has run five miles today.
❌ Incorrect: She has ran five miles today.
Why “Has Run” is the Grammatically Correct Form
Has + past participle = present perfect tense.
The present perfect is used to describe:
- An action completed at some point before now.
- An action that started in the past and is still relevant.
Example:
Marcus has run three marathons since March 28, 2024.
Here, run is the past participle. “Has ran” breaks the grammatical rule because ran is simple past, not past participle.
Why “Has Ran” is Incorrect (But Still Commonly Heard)
People say “has ran” because spoken English often prioritizes speed and habit over correctness.
- Casual conversations normalize incorrect forms over time.
- Regional dialects sometimes influence verb usage.
- The brain often “auto-completes” based on common past tense patterns.
Quote from a language teacher:
“Mistakes like ‘has ran’ persist because they’re repeated, not because they’re correct.”
How Irregular Verbs Work in English Grammar
Unlike regular verbs (walk → walked), irregular verbs like “run” have different forms that must be memorized:
| Verb Form | Example Sentence |
| Base form: run | I run every morning. |
| Simple past: ran | I ran yesterday. |
| Past participle: run | I have run three miles today. |
The past participle form is essential in perfect tenses (has run, had run, will have run).
The Present Perfect Tense and Its Role in Correct Usage
The present perfect tense describes:
- Life experiences (I have run a marathon).
- Changes over time (She has run faster since last year).
- Ongoing situations (He has run the company for ten years).
Structure: has/have + past participle.
Simple Past vs. Past Participle: Breaking It Down
Simple past (ran) → action completed at a definite time in the past.
Past participle (run) → used with auxiliary verbs (has, have, had) to form perfect tenses.
| Tense | Correct Form | Example |
| Simple past | ran | He ran to the store yesterday. |
| Present perfect | has run | He has run to the store three times today. |
| Past perfect | had run | He had run the store before moving. |
| Future perfect | will have run | He will have run the store for five years by next month. |
The Role of Auxiliary Verbs in “Has Run” and “Has Ran”
Auxiliary verbs like has, have, and had act as helpers.
- If you see has/have/had, you must use past participle.
- Without them, you’re likely using the simple past.
✅ She has run to the park.
✅ She ran to the park.
❌ She has ran to the park.
