CTET Class I to V 2015 Feb Paper

The mother tongue, native or first language, is what a person has learned from birth or within a critical period, where the ability to acquire a language is biologically linked to age, and thus becomes the basis for social identity. The mother tongue is an indispensable instrument for the development of intellectual, physical and moral aspects of education. Habits, conducts, values, virtues, customs and beliefs are all shaped through the mother tongue.
