Syntax and Constituency
In my linguistics class we're talking about sentence constituents, and we've been told that if a set of words passes even one constituency test, it is a constituent.
We're supposed to be proving the difference between the verb phrases in "We will [jump off the train.]" and "We will [blow off the class.]", and I know how they're different and I've proved that [off the train] is a prepositional phrase and that [blow off] is a phrasal verb, but we have to use the Sentence Fragment Test, and that one's getting me.
I'm ok with "Where will we jump? [Off the train.]" and I'm fine with saying that "Where will we blow? [Off the class.]" is incorrect. But I can justify asking both "What will we do to the train? Jump off it." and "What will we do to the class? Blow it off."
Which is clearly giving me the wrong answer here, because 'jump off' is not a phrasal verb. What am I missing here? Thank you!
Also, mods, can we have a syntax tag?
EDIT: problem solved :)
