It's the same word used for "thank you" in Swahili, which is widely spoken in Kenya.
You can also use "Kochong'a" which means "thank you" in a more informal way.
Here are some other ways to express gratitude in Kalenjin:
* "Ngai asisinge" - "May God bless you"
* "Mungu akubariki" - "May God bless you" (This phrase is in Swahili, but is commonly used in Kalenjin communities).
Remember that the specific dialect of Kalenjin will influence the exact pronunciation and phrasing.
