gradual

Describes a process of change that happens in tiny, almost imperceptible steps over time. It suggests a smooth transition rather than an abrupt jump or sudden shock. In physical terms, it refers to a slope that is easy to climb because it lacks sharpness or steepness. The feeling is one of ease and stability. Compared to "slow," which can sometimes imply a lack of efficiency or a delay, "gradual" usually carries a neutral or positive connotation of steady, controlled progress.
