A bilingual person is someone who can speak and understand two languages fluently. This ability allows them to communicate effectively in different cultural and linguistic contexts. Bilingualism can occur in various forms, such as being equally proficient in both languages or having a dominant language. Bilingualism can offer several advantages, including improved cognitive skills, better job opportunities, and enhanced cultural awareness. Many countries, such as Canada and Switzerland, have significant bilingual populations, reflecting their diverse linguistic heritage. Learning a second language can also benefit children by promoting better problem-solving and multitasking abilities.
