Hello,
I am working on syntactic trees right now and I have a sentence I need to make a tree diagram for and it has two verbs. One is the verb before the DP (that is what we are using in this class rather than NP) and the other is at the end of the sentence. It is similar to the sentence:
"I know she sings."
The problem is I do not understand how to draw a diagram with two verbs like this. If it had a complementizer then I'd know how to proceed. Can a VP or an IP phrase contain a VP or IP phrase itself? I've never seen a sentence structured that way. Will someone explain this to me?
