improve

This word conveys a positive trajectory of change, focusing on the transition from a suboptimal state to a superior one. It is frequently used in professional, academic, and medical contexts to describe progress or optimization. While similar to "enhance," which often implies adding a specific quality to something already good, "improve" typically suggests correcting a deficiency or raising a baseline standard. It functions both as an active effort to change something and as a description of a natural recovery or growth process.
