Is it drink, drank, drunk or something else?

Jonelle Eligio: just like think, thank, thunk

Bethanie Menden: Yes. That's how it works. I don't think anyone says "swum" anymore, even though it's a perfectly correct word. I think most people would say "I've been swimming" or "I've swam" because swum just doesn't sound right for some reason. And I think because we tend to treat the act of swimming as being in the moment of it, using the past perfect doesn't mesh with that either.

Helen Zafar: Both are fine.

Jimmie Doerfler: You can look this up in any dictionary. A dictionary will tell you the principal parts of any verb. Just look up the infinitive ("drink").
