Language learning is the process of learning to speak and understand a foreign language. It helps children to acquire practical commands of language. It is a result of deliberate and conscious effort for a better understanding of foundational skills of language learning.The language to which a child is predominantly exposed from infancy is known as the mother tongue or first language. Mother tongue supports the learning of a second language as research has shown that many skills acquired in the mother tongue or the first language can easily be transferred to another language.For example, if a learner develops good reading skills in Bengali, he/she is likely to be able to apply these skills to learning English.Hence, it is clear that the mother tongue supports the learning of the second language.
