Immersion refers to being in an environment in which you have constant contact with a language. This may be one's own native language or one that one wishes to learn. There are two types of immersion: natural immersion and artificial immersion. Natural immersion is simply being in an area or environment where a certain language is spoken. An artificial immersion environment is one that is created because the natural environment is not available or possible.

Means of immersion:

  • native speakers;
  • listening to radio;
  • listening to audio books;
  • watching movies and television shows;
  • watching YouTube;
  • reading books/comics/websites/etc;
  • chatting online;
  • listening to music
  • whatever else you can think of.

Several language learning methods make heavy use of immersion. The most famous of these is AJATT.
