Repetitions in a poem can be defined as the intentional use of the same word, phrase, line, or stanza more than once throughout the poem. This literary device can serve various purposes, such as emphasizing a particular theme, creating rhythm, building a sense of urgency, or enhancing the emotion of the poem. Repetition can also help make a poem more memorable and can contribute to its overall structure and flow.
