Erasure poetry is a form of poem created by taking an existing text and removing words, phrases, or sections to reveal new meanings or poems from the original work. The process often involves striking out or blacking out certain parts of the text, leaving behind a selection of words that convey a different narrative or emotion. This technique emphasizes creativity and reinterpretation, allowing the poet to highlight the essence of the source material while transforming it into something uniquely their own.
