constituents

ok a constituent is a break in the sentace of words that go together. for example in the sentance "the pimp gave me a turkey sandwich" the constituents are

the pimp (noun phrase)
gave (diatrasitive verb)
me (noun phrase)
a turkey sandwich (noun phrase)

got it? no? wiki it.

anyways, how do you think these are used in the linebreaks in poetry? is it a consious desicion?
