What is irrealistic?

"Irrealistic" is not a commonly used word in English, and is not found in most dictionaries. It may be a variation of the word "unrealistic," which refers to something that is not based on reality or practicality. It can describe an idea, goal, or expectation that is not feasible or achievable. For example, it is unrealistic to expect to become a professional athlete without putting in the necessary training and practice. It can also refer to a situation or scenario that is not possible in reality, such as a dream or fantasy.
