Bilingualism: Language and Cognition

Bilingualism can be seen everywhere around the globe. There are different reasons for being bilingual for instance, migration, intermarriages, educational, and vocational opportunities. A person who uses at least two languages with some degree of proficiency in both of them is called bilingual. According to Longman Dictionary of Language Teaching and Applied Linguistics bilingual means an individual who can speak, read or understand two languages equally well, but he/she has a better acquaintance of one language than another. Some bilingual people are skillful in both languages they speak, but other bilinguals obviously have a dominant or preferred language. In this study, different degrees and types of bilingualism is examined. To achieve this, document analysis technique was employed through investigating the existing articles about bilingualism.
