From The Collaborative International Dictionary of English v.0.48 [gcide]:
del \del\ n. (Math.)
a differential operator which, operating on a function of
several variables, gives the sum of the partial derivatives
of the function with respect to the three orthogonal spatial
coordinates; -- also called the {gradient} or {grad}. It is
represented by an inverted Greek capital delta ([nabla]), and
is thus because of its shape also called {nabla}, meaning
harp in Hebrew.

From WordNet (r) 3.0 (2006) [wn]:
gradient
n 1: a graded change in the magnitude of some physical quantity
or dimension
2: the property possessed by a line or surface that departs from
the horizontal; "a five-degree gradient" [syn: {gradient},
{slope}]
