UK: ˈɡreɪdiənt | US: ˈɡreɪdiənt
n. a gradual change in a variable quantity, such as color, temperature, or elevation
n. (Mathematics) the rate of change of a function with respect to its variables
n. (Physics) the directional rate of change of a scalar field
The word "gradient" originates from the Latin gradus (meaning "step" or "degree"), combined with the suffix -ient, which forms adjectives denoting a state or process. The term evolved in scientific contexts to describe gradual changes, reflecting the idea of progressing in "steps" (e.g., color gradients, temperature gradients). The logical progression from "step" to "rate of change" highlights how physical or mathematical transitions can be conceptualized as incremental shifts.
