Usage
What does mental mean? Mental is an adjective that means relating to the mind.It is especially used in contrast with physical, which means relating to the body. Mental is commonly used in the context of psychological disorders or the care and treatment of people who have them. One of its most common uses is in the phrase mental health.Mental is sometimes used as a slang term with the same meaning as the informal sense of crazy, especially in the U.K. It’s typically used to describe a person or their behavior as being extreme or illogical in some way. Keep in mind, however, that when used in this way, words like crazy and mental may reinforce harmful stereotypes and associations with mental illness.Example: To be an elite athlete, you have to be physically strong, but you also have to perfect the mental aspects of your game.
