Verbs with irregular past participles

This is a brief list of common Italian verbs with irregular past participles. I felt it was important to ensure I could recognise and use each one in the list, so it then became natural. I've also included some nouns with what seems to be illogically placed definite articles.. it's really good to familiarise yourself with these to prove your knowledge. Eg. Clima. It's il clima, not la clima; which is why it is almost contradictory but grammatically correct.
