Cross fingers的意思

"Cross fingers" is an English idiom that is often used to express hope or wish for good luck. It is a superstitious gesture where a person crosses the index finger over the middle finger, typically done discreetly with the hand hidden or out of sight. This gesture is thought to bring luck or protect against bad fortune.

The origin of this expression is not entirely clear, but it is believed to be derived from the Christian practice of crossing oneself, which is a blessing or a prayer gesture. Over time, this gesture may have been adapted into a more general good luck charm.

Using "cross fingers" can be seen as a mild form of superstition, and it is commonly used in casual conversations, especially when there is uncertainty or a need for luck in a particular situation. For example, a person might say "I'll cross my fingers for you" to someone who is about to take a difficult test or give an important presentation.

It's worth noting that this expression is more commonly used in British English than in American English, where a similar gesture might simply be referred to as "crossing your fingers" without the inclusion of the word "fingers."
