Thank you for such a wonderful question.
As a verb, the word “кой” has a different syntactic position. It can be a predicate and an
auxiliary verb in a sentence.
1) The predicate:
Жерге кой - Put it on the ground
Кол кой - Sign on the document
Бетке кой - Hit him in the face
Келгенди кой - Stop coming
Чеккенди кой - Give up smoking
2) As an auxiliary verb, it gives the enhancing effect of movement and action, depending on the
verb.
Ала кой - quickly take something
The auxiliary verb merges with the main verb in the pronunciation. This is also reflected in the
letter:
Келегой (келе кой)
Жүрөгой (жүрө кой)
Басагой (баса кой)
Талпынагой (талпына кой)
Талп – onomatopoeia; flop.
(Heavily, awkwardly, ponderously, clumsy) movement, action
Талпын – to try, to flap
Талпынып жаңыдан басып келе жаткан бала – toddler; kid tries to walk.
Талпынагой - Let's try to go.
Басагой - Let's go.
They are gentle, affectionate and kind words.
Lastly, I want to ask a question. Why do we write the letter "г" in “келегой”, “басагой”.....?
