A Beginner’s Guide to Passive Language Learning
Osmosis /ɒzˈmoʊsɪs, ɒs-/
The passage of a solvent through a semipermeable membrane… // The gradual or unconscious assimilation or adoption, as of ideas… 
How can one learn a language with little effort…?
I have some advice for you. And if you are a person who is going to live in a foreign country, I think it’s an essential one. It’s one strategy among others, but
This is for you if:

This nerdy expression of ‘learning by osmosis’ is an inference from the biological definition. Many cells and small lifeforms are surrounded by a solutions. Simply by being in that solution, things will pass in and out of the cell through its ‘skin’ (the semipermeable membrane). “Live in a foreign country, and since you are bathed in its native language on a 24/7 basis, you won’t have to study. It’ll just seep into you from the surroundings.”
