History


Early History

William Cameron Townsend, a Presbyterian minister, founded the organization in 1934, after undertaking a Christian mission with the Disciples of Christ among the Kaqchikel Maya people in Guatemala in the early 1930s. In 1933, he turned to Mexico to translate the Bible into indigenous languages there, as he had done for Kaqchikel. Townsend established a working relationship with the Mexican Secretariat of Public Education under the government of President Lázaro Cárdenas (in office 1934–1940) and founded SIL to educate linguist- missionaries to work in Mexico. Because the Mexican government did not allow missionary work through its educational system, Townsend founded Wycliffe Bible Translators in 1942 as a separate organization from SIL. Wycliffe Bible Translators focused on Bible translation and missionary activities, whereas SIL focused on linguistic documentation and literacy education. Having initiated collaboration with the Mexican education authorities, Townsend started the institute as a small summer training session in Sulphur Springs, Arkansas, in 1934 to train missionaries in basic linguistic, anthropological, and translation principles. Through the following decades, the SIL linguists worked at providing literacy education to indigenous people of Mexico, while simultaneously working with the Wycliffe Bible Translators on Bible translation. One of the students at the first summer institute in its second year, 1935, Kenneth Lee Pike (1912–2000), would become the foremost figure in the history of SIL. He served as SIL's president from 1942 to 1979, then as president emeritus until he died in 2000.


Instituto Lingüístico de Verano

The Mexican branch, , was established in 1948.


Kidnapping and murder of Chester A. Bitterman in Columbia

On January 19, 1981, SIL field worker Chester "Chet" A. Bitterman was taken hostage by the left-wing guerilla group M-19 in Columbia who believed SIL was a cover operation for the Central Intelligence Agency (CIA). SIL denied involvement with any government intelligence agency stating that it was against their policy. M-19 demanded SIL withdraw all 209 of its people from Colombia, or else they would kill Bitterman. After 48 days of SIL refusing to yield to the demands, Bitterman was found murdered.


2000 - Present Day

In 2016, Michel Kenmogne from Cameroon became Executive Director. In 2025, Johnstone Ndunde became Executive Director. SIL said it had 1,350 language projects in 98 countries and 4,200 staff from 84 countries.


Contributions

SIL's principal contribution to linguistics has been the data that have been gathered and analyzed from over 1,000 minority and endangered languages, many of which had not been previously studied academically. SIL endeavors to share both its data and the results of its analysis to contribute to the overall knowledge of language. This has resulted in publications on languages such as Hixkaryana and Pirahã, which have challenged the universality of some linguistic theories. SIL's work has resulted in over 20,000 technical publications, all of which are listed in the SIL Bibliography. Most of these are a reflection of linguistic fieldwork. SIL's focus has not been on the development of new linguistic theories, but tagmemics, though no longer promoted by SIL, was developed by Kenneth Pike, who also coined the words emic and etic, more widely used today in anthropology. Another focus of SIL is literacy work, particularly in indigenous languages. SIL assists local, regional, and national agencies that are developing formal and informal education in vernacular languages. These cooperative efforts enable new advances in the complex field of educational development in multilingual and multicultural societies. SIL provides instructors and instructional materials for linguistics programs at several major institutions of higher learning around the world. In the

Methodological contributions


Ethnologue and ISO 639-3 codes

''Ethnologue: A Guide to the World's Languages'' has been published by SIL since 1951. From the 13th edition (1997) onwards, the entire contents of the published book were also shared online. From the 17th edition onwards (2013) the publication shifted to a web-centric paradigm, meaning that the website is now the primary means by which the database is accessed. Among other advantages, this greatly facilitates user contributions. A new edition is now published every February. The 27th edition was released in February 2024 and lists 7,164 languages. Starting with the 16th edition (2009), ''Ethnologue'' uses the ISO 639-3 standard, which assigns 3-letter codes to languages; these were derived in part from the 3-letter codes that were used in the ''Ethnologue'''s 15th edition. SIL is the registration authority for the ISO 639-3 standard. With the publication of the 17th edition (2016), Ethnologue launched a subscription service, claiming that the paywall would only affect 5% of users. Users who contribute over 100 accepted changes are rewarded with lifetime free access. A comprehensive review of the 16th, 17th and 18th editions acknowledged that " thnologueis at present still better than any other non-derivative work of the same scope" except that " tfails to disclose the sources for the information presented.


Software

SIL has developed widely used software for linguistic research. * Adapt It is a tool for translating text from one language into a related language after performing limited linguistic analysis. * In the field of lexicon collection, ShoeBox, the newer ToolBox (Field Linguist's Toolbox), and Lexique Pro have largely been replaced by FieldWorks Language Explorer (FLEx Windows and Linux) for linguists and WeSay (also Windows and Linux) for non-professionals. SIL also provides a "Webonary" website for publishing dictionaries. * Graphite is a smart-font technology and rendering system. * Keyman is a keyboard software solution for typing over 2000 of the world's languages and can be used to make custom keyboards.


Fonts

SIL has developed several widely used font sets that it makes available as

under the SIL Open Font License (OFL). The names of SIL fonts reflect the Biblical mission of the organization "''charis''" (Greek for "grace"), "''doulos''" (Greek for "servant") and "''gentium''" (Latin for "of the nations"). These fonts have become standard resources for linguists working on the documentation of the world's languages. Most of them are designed only for specific writing systems, such as Ethiopic,

It supports a wide range of Latin- and Cyrillic-based alphabets." * Doulos SIL: "a Unicode serif font similar in design to Times/Times New Roman. It contains a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, whether used for phonetic or orthographic needs. In addition, there is provision for other characters and symbols useful to linguists. It contains near-complete coverage of all the characters defined in Unicode 7.0 for Latin and Cyrillic." * Charis SIL: "a Unicode-based font family that supports the wide range of languages that use the Latin and Cyrillic scripts. It is specially designed to make long texts pleasant and easy to read, even in less than ideal reproduction and display environments." * Andika: "a sans serif Unicode font designed especially for literacy use and the needs of beginning readers. The focus is on clear letterforms that will not be easily confused with one another. It supports near-complete coverage for Latin and Cyrillic."

UNESCO Literacy Prizes have been awarded to SIL's work in a number of countries: Australia (1969), Cameroon (1986), Papua New Guinea (1979), Philippines (1991).


Criticism

In 1979, SIL's agreement was officially terminated by the Mexican government after critiques from anthropologists regarding the combination of education and missionary activities in indigenous communities, though SIL continued to be active in that country. At a conference of the Inter-American Indian Institute in Mérida, Yucatán, in November 1980, delegates denounced the Summer Institute of Linguistics, charging that it was using a scientific name to conceal its

and language death. Linguists have argued that the missionary focus of SIL makes relations with academic linguists and their reliance on SIL software and knowledge infrastructure problematic in that respective goals, while often overlapping, also sometimes diverge considerably. SIL does not consider efforts to change cultural patterns a form of cultural destruction and points out that all their work is based on the voluntary participation of indigenous peoples. In the SIL view, ethnocide is not a valid concept and it would lead to pessimism to characterize culture change resulting from the inevitable progress of civilization as ethnocide. SIL sees itself as actively protecting endangered languages by promoting them within the speech community and providing mother-tongue literacy training. Additionally, their expanded interest in preserving threatened languages has resulted in the creation of a Language and Culture Documentation Services Unit.
