Have you ever paused while writing and wondered whether has ran or has run is correct? You’re not alone. This is one of the most common grammar questions in English because the verbs ran and run come from the same base verb but are used in different tenses. Even native speakers occasionally mix them up in everyday writing and conversation.
The good news is that the rule is simple once you understand how verb tenses work. In this guide, you’ll learn the difference between has ran and has run, why one is correct and the other isn’t, real-life examples, common mistakes, grammar tips, and memory tricks that will help you use the correct form every time.
Quick Answer
The correct phrase is has run.
- ✅ She has run five miles today.
- ❌ She has ran five miles today.
The verb run is irregular:
- Base form: run
- Past tense: ran
- Past participle: run
Whenever you use has, have, or had, you must use the past participle, which is run, not ran.
Understanding the Verb “Run”
The verb run is an irregular verb, meaning it does not follow the standard -ed pattern.
Here are its forms:
| Verb Form | Word |
| Base form | Run |
| Past tense | Ran |
| Past participle | Run |
| Present participle | Running |
Learning these four forms makes it much easier to choose the correct tense.
Why Is “Has Run” Correct?
The helping verb has forms the present perfect tense.
The present perfect always follows this pattern:
Has/Have + Past Participle
Since the past participle of run is run, the correct phrase is:
- She has run every morning this week.
- He has run three marathons.
- The company has run successful campaigns for years.
In each sentence, run is the past participle.
Why Is “Has Ran” Incorrect?
The word ran is the simple past tense, not the past participle.
Because of that, it cannot follow has, have, or had.
Incorrect:
- ❌ She has ran.
- ❌ He has ran home.
- ❌ They have ran away.
Correct:
- ✅ She has run.
- ✅ He has run home.
- ✅ They have run away.
This is one of the most common mistakes English learners make.
