Hello people! Has the first phrase the same meaning as the second one? (UK informal) If you say that the penny (has) dropped, you mean that you or someone else suddenly understands or becomes aware of something that you or they did not know about before. She looked confused for a moment, then suddenly the penny dropped and she burst out laughing. I was also told that this phrase -which apparently is British- has its equivalent in American in the phrase "The other shoe dropped/ drop the other shoe". But in checking the origin of the second phrase, I found that both have different meanings, or I am confused? Thank you, Art.
