Okay I'm trying to make a tree and I keep getting stuck and I'm not quite sure where. The structure I'm stuck on is something like "think of the boy as my son" or "think of the president as America's king"
I not sure what to do with the second PP (is it even a PP? AdvP seems wrong but it somehow seems like both?)
I feel like [of the boy] and [as my son] should be sisters in the tree, but I also kind of see [as my son] as being under [of the boy]. Are either of these right? Or close to right? I tried finding an example and can't find anything very similar. Any help would be appreciated!
[S [NP *][VP [V think][V' [PP of the boy][pp as my son]]]] (this seems wrong because of the head sitting like a spec in the VP)
[S [NP *][VP [V think][V' [PP of the boy][V' [pp as my son]]]]] (this seems wrong because a double V'- is that allowed?)
[S [NP *][VP [V think][PP of the boy][pp as my son]]] (this seems wrong because it breaks binary branching)
Then I tried this because it seems to fit nicer, however [as my son] seems to feel more like it needs to be an aspect of 'how' you're thinking. It feels disconnected and misplaced buried in the NP- although it has no reference without [of the boy] so higher seems too important while here doesn't seem important enough.
[S [NP *][VP [V think][PP [P of][NP [D the][N' [N boy][PP as my son]]]]]]
Hopefully you can help point me in the right direction. I'm not in school now so I don't have a teacher/book- just my memories and Google. :)
