Poetry is written
to be understood!
“Poetry is literature designed to convey a vivid and imaginative sense of experience, especially by the use of condensed language chosen for its sound and suggestive power, as well as for its meaning and by the use of such literary techniques as structured meter, natural cadences, rhyme or metaphor.”
Houghton-Mifflin College Dictionary. 1986.
Keep in mind: There always is an audience. Use clues from the poem to determine who could be speaking to whom.
