[Tswusayona Tsamsiyu]

can anyone explain me the uses of ko other than let's. I can't understand it from any of the guides I've read.
so please explain it so I can understand.

[Kemaweyan]

I've never seen the other usage of ko except "let's"...

[Lance R. Casey]

I've never seen the other usage of ko except "let's"...

Canon examples:

• Tsun tutet tspivang ko. They can kill a person, you know.
  
• Awnga sngivä'i ko! Let's begin!
  
• Nga läpivawk nì'it nì'ul ko. Tell me a bit more about yourself.
  
• Nga läpivawk nìno ko. Tell me all about yourself.
  
• Za'u kaltxì si ko! Come and (then) say hello!
  
• Oeng rewonay 'awsiteng tivaron ko. Let's you and I go hunting together tomorrow morning.
  
• Li ko. Well, get to it, then. / Let's get on it. (set phrase)
  

As for ko, I don't know any Japanese but I did have in mind Mandarin ba, a sentence-final particle glossed by Li and Thompson as "solicit agreement." Typical translations of ba are: "Don't you think so?" "Wouldn't you agree?" "Let's . . ." "Why don't you . . ." "I'll do X, OK?" I've used ko for all such things, maybe a bit more widely than ba.

I understand the let's meanings and I know li ko but don't know the other ones (such as in the first sentence).
I don't know what it means solicit agreement, and also didn't see any sentence where ko means "don't you think?".

Ma Lance, oeri eltur tìtxen si...

Ko is like a non-interrogative form of kefyak if I am understanding correctly.

Spoiler: fun sentence

Vulka ke kä ko, ki kä ka ram ko!

[Plumps]

Spoiler: fun sentence

Vulka ke kä ko, ki kä ka ram ko!

How do you come up with these?!
Through in a kllte and you have another k-word

One k-word: komum

[Tswusayona Tsamsiyu]

so if I'm understanding this right, ko is similar to kefyak but when the speaker is sure of the answer (when he isn't asking).

[Yayo]

As someone previously stated, ko solicits agreement. As it has been used as "don't you think (so)", you would essentially be soliciting agreement with the listener.

[MIPP]

It is a bit similar to the english "shall (...)?".

For example: "Close the door, shall you?" or "let's play, shall we?".

That's how I learned about "ko". 

[Tswusayona Tsamsiyu]

irayo ma MIPP. it helps. I think I already understand the use of this fadely.
