I'm sure you won't be surprised if I put my oar in here. And I supose I should put a simple definition like this on my diagram. I will get round to it, honestly.
The word "catenative" comes from the Greek word for "chain". Basically, if a modal or a verb is followed by a non-finite verb it's a catenative. The non-finite verbs are the gerunds and the infinitives.
The complexity comes because there are many different structures:
The modals are followed by the bare infinitive ie without "to". There are also three idiomatic/semi-idiomatic verb-verb expressions:
"Make do", "Let go" and "Dare say", and so on. You can see all this in my diagram.
Extra complexity is introduce by the object, and the word "to".
I can't guarantee that everything is correct yet on my diagram, but you should get the general idea:

But type "catenatives" in a search engine and you should find some good explanations.
For those who aren't already scared off, I've extended my diagram to include other related structures.
I've posted this new verson at:

Can I ask any Americans out there to look at the present subjunctive (Americans use this more than the British.)
Can you understand what I've done with "Minimal change in meaning. Can anyone think of more elegant solutions?
This diagram isn't clickable like the other, by the way.
Finally, I still have:

which was the original diagram, and which I havent finished taking all the info from.
When I have, this will be the main website's URL.
I hope this has helped,

Steven, did I detect a hint of scarcasm in your example using "must"? You've made me very unhappy
