One-Person-One-Language (OPOL) is a linguistic approach in bilingual or multilingual upbringing where a single individual consistently uses one language with one specific person or in a particular context. This method is often employed within families or communities to facilitate language acquisition and maintain clarity in communication. The core principle of OPOL is that each language is assigned to a specific social partner or situation, reducing confusion and helping learners associate each language with its relevant setting.

OPOL contrasts with other bilingual strategies, such as code-switching or mixed-language speaking, by promoting the distinction and separation of languages during interactions. It is believed to support more natural and fluent language development, particularly in children, by providing clear and consistent language boundaries. This technique can aid in the preservation of minority or heritage languages when one parent or community member consistently speaks a different language than others.

Research suggests that OPOL can be effective in fostering bilingual proficiency, especially when caregivers or speakers are committed to maintaining the practice over time. However, success depends on factors such as the consistency of use, the social environment, and the age of language learners. Critics note that strict adherence to OPOL may be challenging in certain social or cultural contexts, and some argue that flexible language exposure strategies can also support bilingual development.

Overall, One-Person-One-Language is regarded as a practical and intentional approach for raising bilinguals, emphasizing clear linguistic boundaries to optimize language learning and retention.
