- n. A slope or incline.
- n. A rate of inclination or declination of a slope.
- n. Of a function y = f(x) or the graph of such a function, the rate of change of y with respect to x, that is, the amount by which y changes for a certain (often unit) change in x.
- n. The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.

- adj. Moving by steps; walking.
- adj. Rising or descending by regular degrees of inclination.

- n. The rate of regular or graded ascent or descent in a road; grade.
- n. A part of a road which slopes upward or downward; a portion of a way not level; a grade.
- n. The rate of increase or decrease of a variable magnitude, or the curve which represents it.
- n. The variation of the concentration of a chemical substance in solution through some linear path; also called concentration gradient; -- usually measured in concentration units per unit distance. Concentration gradients are created naturally, e.g. by the diffusion of a substance from a point of high concentration toward regions of lower concentration within a body of liquid; in laboratory techniques they may be made artificially.
