"Deteriorate" refers to the process of becoming progressively worse or declining in quality, condition, or function. This term can apply to various contexts, such as the physical state of objects, health conditions, or even relationships. For example, a building may deteriorate over time due to weather exposure, leading to structural issues. In health, a person's condition may deteriorate if they do not receive proper treatment or care. This decline can manifest in various ways, such as increased pain, reduced mobility, or worsening symptoms of a disease. Understanding deterioration helps in taking timely actions to prevent further decline.
