Documenting the acquisition of indigenous languages

Area of Science:

• Linguistics
• Language documentation
• Child language acquisition

Background:

• Human language is characterized by remarkable diversity, yet acquisition data exists for only 3% of the world's over 6000 languages.
• Rapid language loss threatens the documentation of indigenous languages, potentially losing data on how children acquire them within two decades.

Purpose of the Study:

• To highlight the critical importance of documenting the language acquisition of the last child speakers of indigenous languages.
• To advocate for a collaborative research effort to establish efficient procedures for documenting children's language diversity worldwide.

Main Methods:

• This paper presents a case for prioritizing the documentation of linguistic diversity.
• It outlines necessary steps for achieving comprehensive documentation of child language acquisition in endangered languages.

Main Results:

• The empirical basis for language acquisition theory is diminishing due to language extinction.
• Urgent, collaborative action is needed to document endangered languages before they disappear.

Conclusions:

• Documenting the diversity of child language acquisition is essential for the future of linguistic theory.
• A global, collaborative approach is required to implement efficient documentation procedures and preserve linguistic heritage.
