Etymology

The name Kökirim is of Turkic origin and consists of two elements:kök — “blue”, “sky”, or “azure” in Kyrgyz and Kazakh, also implying “clear” or “pure”; irim — a folk-geographical term widely found in Central Asian Turkic languages.
According to Murzaev, *irim* denotes a “deep pool, backwater, quiet reach, or slow-flowing stretch of a river”.
Konkaşpaev further identifies *irim* as meaning “riverbed, meander, or quiet pool,” and notes its appearance in numerous hydronyms such as *Irtysh*, *Irgyz*, and *Kökirim*.
Hence, the hydronym Kökirim may be interpreted as “blue pool,” “blue bend,” or “calm stretch of the river.”
The name likely refers to the river’s clear water and gentle, meandering course through the Toguz-Toro valley.
