Differentiate between functional bilingualism and language background
Functional bilingualism refers to a person's ability to use two languages proficiently for various purposes, such as communication, reading, writing, and comprehension. It indicates that an individual is fluent in both languages and can navigate different linguistic contexts comfortably.
On the other hand, language background refers to a person's history, experience, and exposure to different languages. It includes factors such as the languages spoken at home, the educational background in different languages, the duration of exposure to different languages, and the level of proficiency attained in each language.
In summary, functional bilingualism is about a person's ability to use two languages effectively, while language background encompasses a person's history and experience with different languages.
