Bilingualism is the ability to use two languages proficiently, whether in speaking, listening, reading, or writing. This concept encompasses various forms of language use, including simultaneous bilingualism, where an individual learns two languages from early childhood, and sequential bilingualism, where a second language is acquired after the first. Bilingualism plays a significant role in second language acquisition, influences social and cognitive development, and intersects with the emergence of pidgins and creoles as new language forms.
