Cross my finger意思

"Cross my fingers" is an English expression that means to wish for good luck or to hope for something to go well. It is often used as a gesture where a person crosses the index finger over the middle finger, usually while saying the phrase. This gesture is thought to originate from the Christian practice of crossing oneself, but it has become a more general superstition for wishing luck. When someone says "cross my fingers," they are essentially saying "I'm hoping for the best outcome," and the gesture is a way of physically expressing that hope.
