Meaning

不快 literally means 'not happy' and describes a state of displeasure, unhappiness, or physical discomfort. It can refer to emotional dissatisfaction, interpersonal friction, or a feeling of being unwell. The term is more formal than casual spoken alternatives.

Usage

不快 is used in both written and spoken contexts, though it sounds somewhat formal. It commonly describes interpersonal tension (心中不快 'feeling displeased') or physical discomfort (身体不快 'feeling unwell'). In modern usage, 不高兴 or 不舒服 are more common in everyday speech for emotional and physical discomfort respectively.
