A native speaker is someone who learned to speak a language as part of their childhood development. A native speaker's language is usually the language their parents speak and/or the language of their country of origin. It is the only language of a monolingual person, and likely the first language of a multilingual person which is acquired naturally in their native environment. It may serve as the basis for their sociolinguistic identity.
A native speaker of a language has the following traits:
Many employers of language teachers prefer native speakers.
While the traditional definition of a native speaker is tied to early childhood language acquisition, some linguistic researchers argue that native-like proficiency can be achieved later in life through full immersion and mastery.
A speaker who meets the following criteria may be indistinguishable from a native speaker, despite learning the language beyond childhood:
This perspective aligns with research in second language acquisition and the concept of near-native proficiency, where individuals acquire full linguistic competence comparable to those who learned the language as their first language. Studies in applied linguistics suggest that sustained immersion and high-level practice can result in functional nativeness, even if the language was not acquired from birth.
While traditional definitions emphasize early exposure, some scholars advocate for a distinction between biological nativeness (acquired in childhood) and functional nativeness (achieved through extensive mastery).
