Report How long do you think it would take you to learn a new language? in Language Learning Posted May 22, 2014 It depends on how much fluency you are talking about. It would take me many years to be perfectly fluent and native sounding. But i think it would take me only one year, with total immersion, to be able to speak fluently in a non-perfect way. I did a study abroad in Italy for a summer. By the end I was surprised how good I got and how quickly it happened. It took me years to learn what I did that summer in the States.
