2. A first language (also native language, mother
tongue, arterial language, or L1) is the language(s) a
person has learned from birth or within the critical
period, or that a person speaks the best and so is often
the basis for sociolinguistic identity. In some
countries, the terms native language or mother tongue
refer to the language of one's ethnic group rather than
one's first language. Sometimes, there can be more than
one native or mother tongue, (for example, when the
child's parents speak different languages)
