Explanation
Careless means not paying enough attention or being too relaxed about something, which can lead to mistakes, accidents, or damage. A careless person might forget important details, leave things in unsafe places, or act without thinking about the results. Being careless is the opposite of being careful, and it often causes unnecessary problems. For example, spilling juice because you weren’t holding the cup properly is a careless action.
