I can help you but What are you asking exactly? Just a little bit more detail in what you want to know. Which variant of generative. Universal grammar , Principle and Parameters, Minimalist..? Which phrase? I'm looking for a teacher in linguistics so S -> NP VP PP, NP -> N -> I, VP -> aux V -> am looking, PP -> PP NP->PP For -> D N -> a teacher ->PP -> P N -> in linguistics. (I'm a bit rusty on that diagram) or more like a tree diagram. or Minimalist view. TP (infinitival verb phrase) -> PRN (I) T" T(am) VP-> V (looking) PP -> P(for) DP -> D(a) N(teacher) PP -> P(in) NP->N (linguistics) Let me know or PM me so we can discuss it further.
