The word 'skeptical' means that someone is unsure about something and doubtful that it is true. You can use it when you are not sure if something is true or believable, and you want to express your doubts about it. For example, if someone tells you that they can make you rich easily, but you are not sure if it's true or not, you can say "I'm skeptical about that claim." This word is commonly used in scientific discussions when people are not sure if a theory is correct or not.
