Linguists may support beginning instruction in a second language in elementary school rather than high school because when you are younger, you have a greater ability to learn. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
When the individual is in elementary school, they are still experiencing language development while an individual in high school, has already experienced it. Because of this, it would be easier for the individual in elementary school to learn a second language because their first language is not yet fully developed. The individual in elementary school will also become more fluent with both languages.
