Greater grasp of one's first language
Most of the time we use our first language with little thought to grammatical rules or constructions. This is perfectly natural, but the experience of learning a new language can bring greater understanding and perhaps even better grammar to our first language. Knowing the way another language works encourages us to examine our own language’s mechanics in a positive way. By being able to compare the two, we learn more than we ever would as a monolingual. Or as Nancy Rhodes, Director of Foreign Language Education at the Center for Applied Linguistics in Washington, DC says, “The more children learn about a foreign language, the more they understand about their own language.” Children use what they learn in one language to reinforce concepts and terms they’ve learned in the other. They can solidify their gains in their native tongue by matching them to their new adventures in another language.
