What Age Is Best To Learn A New Language At?
Learning a new language can be hard if you are older or if you have already gone through puberty. Study shows that the best time to learn a new language is between the age 2 and when the brain is developed (Puberty). Young learners are most likely to develope a native accent and yes older learners can use strategies and tactics to learn a new language but young learners have less to learn to be proficient.
Relations Between Languages
Being proficient in a language means you can write, speak, and listen to other people in that language. It may take 2-3 years just to be proficient but to be able to do all those things at an academic level it could take anywhere from 4 to 10 years. You can pass on skills from each language. For example I'm a good writer and I will probably also be a good writer in Spanish because they have the same concepts.
