Tree diagram

[Nuh Yamin]

Hi,
Could you help me draw a tree diagram of the following sentences:
1. I know you know what they know about the secret
2. I am aching for my old friend
3. She had tried the suit on
I'd appreciate your help

 

[Frank Antonson]

I can't help you with a tree diagram, but that first sentence looks like a fun one to R-K.

I'll work on that one later.

 

[chester_100]

Have fun!

 

[Nuh Yamin]

Have fun!

Thank you very much, Chester. That's very kind of you.
