The French word “coup” means “knock” or “blow,” however it is used in French expressions much more often than this humble meaning would suggest. A few of these French expressions such as “coup d’état” and “coup de grâce” have even been adopted into English, but there are far more in use in French. Some expressions using "coup de" are simple to decipher, but others are more idiomatic. By mastering these "coup de" expressions, you can learn how to communicate in French on subjects from sports to weather.
The simplest of these expressions are the most straightforward – “coup de coude” or elbow blow, means “ nudge” and “coup de pinceau” means “ brush stroke.” Nonetheless, some of the most interesting French idiomatic expressions use “ coup de” as well. One romantic example is “coup de foudre.” This would literally mean “lightning strike” but instead, it is best translated as “love at first sight.” In a similar vein, “coup d’oeil” means “glimpse” or “view.”
