Interlanguage fossilization
Adults' learning style: Interlanguage fossilization occurs in adults learning a new language. In language learning, unlike the child, adults can't ignore about language rules and grammar. When adults study a new language, they always check the language rules or grammar. This can make learning a language much harder. In addition, adults are more likely to be influenced by their native language. In other words, the native language interferences hold adults back from improving language proficiency. Therefore, there are many adults language learners who experience the interlanguage fossilization.
