Definition of grimace

The word "grimace" comes from the French word "grimaçon," which literally translates to "grinning." The French word, in turn, derives from the Latin word "grimate," which meant to laugh or show teeth. In the 1500s, the English began to adopt some French words, including "grimaçon," which they eventually anglicized to "grimace." Initially, "grimace" referred to a theatrical expression or facial contortion, often used to mimic a mocking smile or snarl. Over time, the meaning of "grimace" evolved to describe a face that reflected an expression of discomfort, pain, or disgust. This development may stem from the fact that users of the word now associate a grimace with facial contortions that indicate physical discomfort, such as those made by someone in pain. In modern-day English, "grimace" is still used to describe an involuntary facial expression that conveys discomfort, annoyance, or distaste, but it now primarily pertains to facial expressions made as a response to experiencing pain or discomfort.
