Turkish was treated as the primordial language from which the world's other languages ultimately developed.

Current understanding
Current understanding
Turkish belongs to the Turkic language family and is not the ancestor of all human languages. Historical linguistics reconstructs multiple language families and earlier forms through systematic patterns of sound change, grammar, and documented descent; the Sun Language Theory has no evidentiary basis.
Institutional episode
Turkey
The Sun Language Theory was promoted through the state-backed Turkish Language Association and became a central subject of the Third Turkish Language Congress in 1936. The congress proceedings treated it as a new linguistic school and organized a dedicated commission around the theory. It proposed a primordial role for Turkish in the origin of language and was supported for political and national-cultural purposes before being abandoned.

Institutional machinery
The Turkish Language Association was the principal institutional carrier. Its Third Turkish Language Congress in 1936 made the Sun Language Theory a formal subject of institutional linguistic work, including a dedicated Güneş-Dil Teorisi ve Dil Karşılaştırmaları Komisyonu. The broader language-reform establishment and state sponsorship are described here rather than listed as if they were separate institutions.
