Perhaps you mean, how does one write a poem? That is not a question which is easy to answer.

Perhaps you could learn something by visiting the Poetry Forum at this site--which you can visit by clicking here. There you will find many threads devoted to the subject of poetry.

If I ever decide to become a teacher, I'm going to send all my students to online forums so they can learn things I'm too lazy to teach.

Go forth, little ones, and GOOGLE!
