The Vietnamese word "ủ dột" is an adjective that describes a feeling or atmosphere that is sullen, dull, or gloomy. It often refers to someone who appears sad or depressed, or to a situation that feels heavy and lacking in joy or brightness.
In a more advanced context, "ủ dột" can be used in literary works or poetry to convey deeper emotional themes, such as loss or despair.
While "ủ dột" primarily means sullen or gloomy, it can also imply a sense of heaviness or a lack of energy. It does not have a positive connotation and is generally used to express negative emotions or moods.
