Many English learners wonder whether they should say has run or has ran. The confusion is understandable because the verb run is irregular, meaning it does not follow the normal -ed pattern like walked or played. Instead, its different forms change in ways that can be difficult to remember.
The good news is that the rule is actually very simple once you understand the three forms of the verb. In this guide, you’ll learn the difference between has run and has ran, when to use each one, common mistakes to avoid, memory tricks, American vs. British English differences, and plenty of real-life examples. By the end, you’ll know exactly which form is grammatically correct every time.
Quick Answer
“Has run” is correct. “Has ran” is grammatically incorrect in standard English. After has, have, or had, always use the past participle, and the past participle of run is run, not ran.
Correct: She has run five miles today.
Incorrect: She has ran five miles today.
Why People Confuse It
Many people mix up has run and has ran because ran is the simple past tense of run, while run is also the past participle.
Here are the three forms:
- Base verb: run
- Simple past: ran
- Past participle: run
Since many irregular verbs have different past and past participle forms, learners often assume ran should follow has, but that’s not how English grammar works.
First Word: Has Run
Meaning
Has run is the present perfect tense.
It describes:
- An action completed at an unspecified time
- A recent action
- An experience
- Something that started in the past and has relevance now
Structure
Has + past participle (run)
Examples
- She has run every morning this week.
- The machine has run without problems.
- He has run three marathons.
- My phone has run out of battery.
- The software has run perfectly since the update.
Second Word: Has Ran
Meaning
Has ran is not correct in standard English.
Why?
Because has must always be followed by the past participle, not the simple past tense.
Wrong:
- He has ran.
- She has ran fast.
- The dog has ran away.
Correct:
- He has run.
- She has run fast.
- The dog has run away.
