Repetition in poetry refers to the use of the same word or phrase multiple times and is a fundamental poetic technique. It is a powerful literary device that can highlight important ideas, flesh out those ideas, and make writing more musical and memorable. Repetition can be used to help establish rhyme schemes, emphasize a particular point, or point out contrasting uses of a given word. It might seem counterintuitive to repeat words or phrases, but when used correctly, repetition can have powerful effects in literature. Repetition is not defined as one single "thing" in a poem and can differ greatly depending on the poet, what theyre writing about, the format, and the way in which repetition is used. There are many different types of repetition in poetry, including anaphora, epiphora, anadiplosis, and chiasmus. Repetition is a primary way of creating a pattern and is one of the most marked features of all poetry, oral and written.
