The Three Essential Forms of Run – Your Quick Reference
Every English verb has multiple forms, and run is an irregular verb that doesn’t follow standard patterns. Here’s what you need to memorize:
| Form | Example | Usage |
|---|---|---|
| Present tense run | I run every morning | Current actions or habits |
| Past tense ran | She ran yesterday | Completed past actions |
| Past participle run | They have run the marathon | Perfect tenses and passive voice |
Memory trick: Think “Run today, ran yesterday, have run before.” This simple phrase helps you remember that the past participle returns to the same spelling as the present tense.
The present participle running adds “-ing” to show ongoing actions. Unlike many verb conjugation rules, run keeps its unique pattern across all tenses.
