Freeverse
Definition:
Freeverse is a special type of poem. There is no noticeable rhyme pattern and no specific rhythm or line length. Freeverse poems are essentially "free" of rules.
Example:
Fog by Carl Sandburg
The fog comes
on little cat feet.
It sits looking
over harbor and city
on silent haunches
and then moves on.
The bolded part of this poem is the part that explains why this is Freeverse. There are sentence fragments, choppy rhythms, and no rhyme pattern. All of these attributes make up a Freeverse poem.
