If you’re unsure whether to write has ran or has run, you’re not alone. This is a very common grammar mistake because both ran and run are forms of the verb “run.” But only one works with has/have/had.
The correct form is has run. The phrase has ran is grammatically incorrect in standard English. Let’s break down why so it becomes easy to remember.
Quick Answer: Has Ran or Has Run
- Has run ✅ Correct
- Has ran ❌ Incorrect
- Use has + past participle (run)
- “Ran” is simple past, not used with “has”
Example:
- He has run five miles today.
- She has run this race before.
Understanding the Verb Forms of “Run”
To understand this clearly, you need to know the three main forms of the verb:
- Base form → run

- Past participle → run
So:

Why “Has Run” Is Correct
