Is runned a word?

No, runned is not a word. “Run” is an irregular verb.

 

  • The past participle form is the same as the infinitive (e.g., “Have you run all the way here?”)
  • The simple past tense form is different to the infinitive, but the only change is a single altered vowel sound (e.g., “I ran all the way there but she had already left”)

 

This is the same conjugation pattern as the verbs “come” and “become.”
