என்னுடைய கல்லூரி நாட்களில் நான் புகைபிடித்தேன். (ஆனால் இப்போது இல்லை.)

இதை எப்படி இங்கிலீஷ்ல சொல்லுவீங்க?

Answer
I used to smoke during my college days.
“Used to” means “not now.” It is equivalent to “I smoked during my college days but not now.”

When talking about facts that are no longer true, we say “used to.” It may refer to repeated actions and a condition or set of circumstances.
For example, Raju used to play cricket for the local team, but he is now too old.
