A dedicated linguist, Sarybayev made significant contributions to studying dialects, especially within Turkic languages, by documenting regional variations and forgotten words.
Experts note that Sarybayev was the first in the Turkic world to defend a doctoral dissertation in dialectology. His work remains a valuable resource for ethnographic and linguistic studies. A commemorative conference was recently held in his hometown, Tashkent, gathering scholars from across Central Asia.
