这个短语的字面解释是“交叉手指”，这是什么意思呢？请看对话：

    A: How are things going with your soccer tournament?

    B: We’ve got all things ready. Now we’re crossing our fingers and hoping that the weather stays fine.

    Note: This idiom means to “hope that something happens the way you want it to.” It’s thought that the act of crossing one’s fingers started when Christianity was in its infancy. At this time, Christianity was outlawed and dire consequences befell people who showed support for it. Early followers were forced into secrecy and they are known to have developed signs and symbols that allowed them to recognize each other. They probably made a cross with another person, sort of like a secret handshake. In this case, each member would present their thumb and index finger in the shape of an “L.” Their thumbs would touch, and their index fingers would cross, making a symbol like today’s Christian fish symbol.
