I have a sentence that I would like parsed (by a human). It's a
sentence I found in the Economist. One of my students asked me to
parse it, but I've found that it's been much too long since I've done
any diagramming. I would like it parsed in similar
fashion to the way it's done in Max Morenberg's book 'Doing Grammar'.
Here's the sentence: "However, a breakthrough came when he realised
that what he had been thinking of as different parts of speech were,
in fact, grammatically the same."
