I have watched Stephen Krashen's talk on language acquisition.
And I learnt that according to decades of research and experience, the best way to pick up a new language is to acquire - just like children do - via comprehensible input.
This works great when interacting with language partners / parents, or when watching videos online where one can see things being shown or pointed at.
My question is:
- How can one acquire a language when watching or seeing is not an option?
