What is bilingualism?

Bilingualism is the ability to communicate in two different languages, using two languages in some proportion, in order to facilitate learning by student who have a native proficiency in one language and are acquiring proficiency in others. There are many definitions of bilingualism, for example, a person does not have to speak both languages with equal fluency to be a bilingual. It is very common for bilinguals. Some people have been bilingual since birth, due to their parents. I define bilingualism simply as using two languages depending on the fluency of second language.
Fluency in a second language requires skills in listening comprehension, speaking, reading, and writing. Some bilinguals are people who were thought by parents who can each speak a different language at home and by friends who spoke different language in school. In some countries like Malaysia, especially those with two or more official languages due to the multi racial, schools encourage bilingualism by requiring intensive study of a second language.
In Malaysia, we can learn many languages due to mix marriage, friends, schools and many more. This happen to a lot of students and it is an easy way to learn when you come from a different background. Having the ability to be bilingualism or multilingualism is a great advantage because this will allow you to suit any environment at any time. Thus, you will have the benefits of job for your ability of speaking skills. I personally feel, learning a language is fun and the easiest way for it helps you a lot in future.
