Which is the best to learn any language within in week?
Hindi.... :P (indian language maybe!!!)That's 'cauz it's very similar to sanskrit, which is obviously the mother of all language!!
Depends where you live. If you live in the States you can learn Spanish. Good course program is Rosetta Stone
Hindi!! u already learnt some!!!
you cant learn a language within a week. it takes months if not years. but spanish is the easiest and fastest
