Passive bilinguals are individuals exposed to a second language without actively using it. In many homes, one language, usually the heritage language, is spoken predominantly while children absorb a second language through media, peers, or education. This results in understanding the second language but lacking speaking and writing skills. Supporting passive bilinguals involves nurturing their home language, which strengthens cultural identity and future language development. Families can enhance children’s linguistic abilities by creating opportunities to engage with their home language through books, conversations, and cultural activities, fostering confident communicators in a multilingual world.
