How can I learn a new language?

I'm going to jump to the conclusion you're Italian, based on your writing style.
I'd suggest downloading an app like babel or duolingo and as you progress look for supporting YouTube videos. For example if a lesson is on "colours" find a video on Spanish colours.
I think there are some language apps you can download to help you... try researching it and see which one suits you best.
