A miserable person feels unhappy and disappointed most of the time.
When we describe someone or something as miserable, we usually mean that it's really unfortunate or unlucky. For example, if you have a long, stressful day at work and feel terrible when you get home, your family might say you look really miserable. It can also be used to describe a situation where things aren't going well - like being stuck in traffic during rush hour. In both cases, the word emphasizes that something is not good and feels unpleasant.
In a state of misery: very sad, ill, or poor.
