This may not cause you to change your mind about anything, but the fact 
is that you are not the only person that has complained about "parts of 
speech" in English descriptions of RDF examples not always being 
parallel with the "same-named" parts of the RDF expressions themselves. 
  We had several comments about that on earlier versions of the RDF 
Primer, so we changed the English descriptions around to make them 
parallel.  The result is that the English isn't as natural as it might 
be (we are talking here about making the English parallel to an 
artificial language, after all), but the subjects, objects, and 
predicates match up (or match up better anyway).  Check out the Primer 
at http://www.w3.org/TR/rdf-primer/ and tell us if you still think it's 
confusing (this sort of plug being part of my job as Editor!).
