English grammar may look simple at first, but small verb changes can create big confusion. One of the most common examples is “run vs ran.” Many English learners—students, writers, and even fluent speakers—often pause and ask themselves: Should I say “I run,” “I ran,” or “I have run”? This confusion happens because run is an irregular verb, and its forms do not follow normal -ed rules.
In everyday conversations, people frequently mix up run and ran, especially when talking about past events. You might hear sentences like “I have ran late” or “The business is ran by him,” which sound natural to some learners but are actually grammatically incorrect. Understanding the correct use of run vs ran is important not only for exams and writing, but also for speaking clear, confident English.
From real classroom teaching experience, this topic is one of the most repeated grammar mistakes among ESL learners. The reason is simple: run works as both a present form and a past participle, while ran works only as the simple past tense. Once this difference becomes clear, the confusion disappears quickly.
In this guide, you will learn the meaning, tense rules, real-life examples, common mistakes, and easy tricks to remember when to use run and when to use ran. Whether you are preparing for exams, improving spoken English, or writing professionally, mastering run vs ran will make your English more accurate and natural.
