The word 'lethargic' is used to describe a feeling of being tired, sluggish, and lacking energy. You can use this word when you or someone else is feeling lazy and not interested in doing anything active or productive. For example, if someone stayed up late and had a long day at work, they might feel lethargic and not want to go for a run or do anything that requires a lot of effort. It is important to note that lethargy can also be a symptom of an underlying medical condition, so if you or someone you know experiences it frequently, it might be worth consulting a doctor.
