Question

What is the meaning of give one's right arm?
"I would give my right arm to get an A on my final exam!" Roxanne exclaimed.

Answer 1

The expression "give one's right arm" is an idiomatic way of saying that someone is willing to make a significant sacrifice or go to great lengths to obtain something they strongly desire. In the context of Roxanne's statement, she is emphasizing how much she wants to get an A on her final exam by suggesting that she would be willing to sacrifice something very valuable (her right arm) to achieve that goal. It's a figurative expression and not meant to be taken literally.
