Interlanguage fossilization
Acceptance: Acceptance of a new culture can also cause interlanguage fossilization. If the learners are in new country, then they have to learn a new language. When the learners are in new cultures, they try to make it suitable themselves to new circumstances. At first, they feel nervous because there are big cultural differences. Therefore, the learners study hard. However, after time goes by, people stop studying a new language because they cannot feel nervous anymore. The learner think that they are fully adapted in the new culture and they are confident with their new language proficiency. Then, interlanguage fossilization happens.
