I have to write a poem with one line from macbeth and use each word from the line as the first word in each line of the poemex. fair... is ......

The first thing in writing a poem with a line from
Shakespeare's Macbeth (which could be very interesting depending on
the line you choose) is whether you have to write a sonnet or write in iambic
pentameter. As you do not indicate either, I expect any poem will
do.

For the example you have provided, the line is very
famous. It is a paradox: how can something be fair and foul at the same time. And in
this case, "fair" means good and "foul" means bad.

You
could write a poem about Duncan entering the castle: something about the weather being
fair that day; that it is deceiving because of
what the Macbeth's are planning, and that it becomes foul when
Duncan is murdered.

The line with "and" could simply state
"and Duncan's sons flee"... thinking they might be
next.

For foul with its second use you
could refer to how people feel about Macbeth by the end of the story; everyone
is afraid to get close to him for fear of dying. He
is desperate to see the witches for a new set of
predictions. Fair for the last line could describe how everyone
feels once Macbeth dies and order is restored in the universe, and Duncan's son is
restored to the throne.

The nice thing about this
assignment is that the quote can pertain to any part of the story. Good luck with this
assignment.
