“Glum” is an adjective used to describe a person or a thing that is characterized by sadness or a lack of cheerfulness. It suggests a quiet and reserved state of mind, often accompanied by a downcast expression or a dull tone of voice. People who are feeling glum may seem uninterested or unresponsive, and may not engage in conversation or activities as readily as usual.
