A moan is a low, sad sound that someone makes when they're feeling unhappy or uncomfortable. You can make a moan when you hurt yourself or are feeling really sad.
When people talk about moaning, they often mean making that sad sound over and over again. For example, if someone's been feeling sick for days, they might start to get frustrated and start moaning about how they don't feel better yet. It's like a way of expressing their unhappiness or discomfort. If you're feeling really tired after a long day, you might let out a big sigh and start moaning about not being able to sleep.
