Repetition is when a sound/word/phrase/line is repeated in a poem. Poets use repetition to emphasize an idea or convey a certain feeling. For example:
Bob ate a fish,
Bob's pig flew above the fish,
Bob ate a fish
In the above example, "Bob ate a fish" is repeated for emphasis. In the course of one day, you will probably see many people use repetition to emphasize something. For example:
He ate my fish! He ate my fish!
When a sentence is repeated, the second time it is said, it is usually emphasized differently. In the above example, the second time the sentence is said, there should be an emphasis on "ate" and "fish".
Contray to a certain saying, repetition is not the death of the soul. When something is repeated, you are more likely to remember it.
