English Wikipedia has an article on:

Nef line bundle

Wikipedia

1. (algebraic geometry) Of a line bundle on a complete algebraic variety over a field: such that the degree of its restriction to every algebraic curve in the variety is non-negative.
   • 1983, Miles Reid, “Minimal Models of Canonical 3-Folds”, in Advanced Studies in Pure Mathematics, volume 1, page 131:

     […] this condition is the numerical consequence of the condition that for some ${\displaystyle m>0}$, the linear system ${\displaystyle |mD|}$ is effective and free; thus nef = "numerically (effective and free)".
