Concept:Multilingualism is the approach that uses the learner's home language as a base to gradually introduce additional languages in school.
Explanation:Multilingualism does not mean learning many languages at random.
It also does not mean sticking only to the mother tongue or home language.
Instead, it starts with the child's first language.
Then, it systematically adds more languages in the school environment.
This method builds on existing linguistic knowledge.
It ensures a smooth transition from home to school language.
Multilingual children show better cognitive flexibility and creativity.
They also perform better academically than monolingual children.
Hence, the correct definition is beginning with mother tongue and then adding more languages in school.
Answer:C. starting with mother tongue/home language and move on to add more languages in school.
