1. He stopped smoking.
2. He quitted smoking.
Are both the same sentence?
Does #1 mean that he decided not to smoke again or mean that he turned the cigarette off after smoking for some time?
Both sentences mean the same thing. BUT the word would be "quit", not quitted. The three parts of the verb "to quit" are quit, quit, and quit.
There is no change with tense change.
The sentences mean that at one time he was a smoker and now he isn't.
