Answer:
When Elizabeth Barrett Browning writes in Sonnet XLII that "My future will not copy fair my past" she means that her future will not be the same as her past.
Step-by-step explanation:
Elizabeth Barrett Browning was a poet during the Victorian Era. In her "Sonnet XLII" she writers that "my future will not copy fair my past" to indicate a phrase she wrote when she was young, stating that her future was not going to be the same as her past. She remembers that memory of her writing that phrase when she was older and believed she was about to die, when actually she was about to be saved by love.
