The verb run has three main forms: run (base form), ran (simple past), and run (past participle). Learning these forms makes it much easier to use the verb correctly in different tenses.
Can I use “has ran” in casual conversation?
Although you may occasionally hear has ran in informal speech or regional dialects, it is not accepted in standard English. In school, professional writing, and formal conversations, you should always use has run instead.
How do I remember the correct form?
A simple way to remember is that has, have, and had always take the past participle. Since the past participle of run is run, the correct phrase is has run. Avoid pairing has with ran.
