One of the more widely accepted definitions of native speakers is that they were born in a particular country (and) raised to speak the language of that country during the critical period of their development.[5][not in citation given] The person qualifies as a "native speaker" of a language by being born and immersed in the language during youth, in a family in which the adults shared a similar language experience to the child.[6] Native speakers are considered to be an authority on their given language because of their natural acquisition process regarding the language, as opposed to having learned the language later in life.
