Which words describe the definition "having a strong desire for revenge"?
I found this word somewhere a few days ago, can't remember where, and I looked it up on Google's dictionary or Siri, and I meant to take note of it, and I forgot about it until now. However, I can't remember what word it was, but I remember the definition. I tried searching for it using my browser's history, but it doesn't show up. For example, I want to say, 'my friend is or was, (adjective) or is a(n) (adjective noun). No, it's not vengeful. It's something else.
