DEL Important Announcements

The Documenting Endangered Languages (DEL) program now has two solicitations. This program website and its solicitation NSF 18-580 are for the main DEL program which provides funding opportunities for DEL Senior Research Grants as well as for Fellowships.  

The other solicitation NSF 16-617, Documenting Endangered Languages - Doctoral Dissertation Research Improvement Grants (DEL-DDRIG) provides information for doctoral students and their advisors planning to submit DDRIG proposals to the DEL-DDRIG program.

Frequently Asked Questions (FAQs) for the Documenting Endangered Languages (DEL) Program are now available and can be accessed via publication

A new series of DEL Outreach videos freely available on YouTube introduces aspects of the National Science Foundation's Documenting Endangered Languages program.

This funding partnership between the National Science Foundation (NSF) and the National Endowment for the Humanities (NEH) supports projects to develop and advance knowledge concerning endangered human languages. Made urgent by the imminent death of roughly half of the approximately 7000 currently used languages, this effort aims to exploit advances in information technology to build computational infrastructure for endangered language research. The program supports projects that contribute to data management and archiving, and to the development of the next generation of researchers. Funding can support fieldwork and other activities relevant to the digital recording, documenting, and archiving of endangered languages, including the preparation of lexicons, grammars, text samples, and databases. Funding will be available in the form of one- to three-year senior research grants, fellowships from six to twelve months, and conference proposals. Note: a conference proposal should generally be submitted at least a year in advance of the scheduled date of the conference. For additional information about creating and submitting conference proposals to the DEL program, please refer to Chapter II. D.7 of the NSF Proposal & Award Policies & Procedures Guide.


This program provides educational opportunities for  Undergraduate Students, Graduate Students, Postdoctoral Fellows. Individuals interested in applying for funding should see the program guidelines above.
