Consider the following sentence:
"Ich rufe dich an".
It is a very simple Standard German sentence with the verb "anrufen", the unusual thing about it is this prefix that comes with the verb, it goes to the end. Does it have any syntactic classification? Or is it considered just a part of the verb that was moved?
If it is just a movement, how would it be represented in a tree using X-bar theory? Would it be in the specifier, a complement, or the core of a phrase, if so, what kind of phrase?
