Multilingualism refers to the ability to use and understand multiple languages. It involves proficiency in two or more languages and is common in many regions of the world. Multilingualism offers cognitive, social, and economic benefits, such as enhanced problem-solving skills, greater cultural awareness, and increased job opportunities. In education, promoting multilingualism involves encouraging language learning, providing resources for heritage language maintenance, and supporting bilingual or multilingual instruction. Multilingual individuals can switch between languages based on context and audience, enriching their communication abilities.
