English verbs can be confusing, especially when irregular verbs are involved. One of the most common grammar questions learners ask is whether they should write has run or has ran. Since both words come from the verb run, it’s easy to assume either form works after has.
The truth is much simpler than it seems. Once you understand how irregular verbs change in different tenses, you’ll never mix them up again. This guide explains the difference between has run vs has ran, provides clear examples, highlights common mistakes, and gives you an easy trick to remember the correct form.
Quick Answer
Has run is the correct phrase because run is the past participle of the verb run. Has ran is grammatically incorrect in standard English because ran is the simple past tense, not the past participle. Always use has/have/had + run, not has/have/had + ran.
Why People Confuse It
Many English verbs simply add -ed to form the past tense and past participle. However, run is an irregular verb.
Its forms are:
- Base form: run
- Past tense: ran
- Past participle: run
Because ran already refers to the past, many learners mistakenly use it after has, have, or had.
First Word: Has Run
Has run is the grammatically correct expression.
It uses:
- Helping verb: has
- Past participle: run
This combination forms the present perfect tense, which connects a past action to the present.
Examples
- She has run five marathons.
- He has run this business since 2015.
- The dog has run into the garden.
- My brother has run out of patience.
- Sarah has run every morning this week.
Second Word: Has Ran
Has ran is incorrect in standard English grammar.
Although you may hear it in casual speech or regional dialects, it should never appear in formal writing, exams, or professional communication.
❌ He has ran home.
✅ He has run home.
❌ She has ran a marathon.
✅ She has run a marathon.

American vs British English
