Definition:Generator of Module/Also known as

Definition
A generator of a module is also known as a spanning set.

Some sources refer to a generator for rather than generator of. The two terms mean the same.

It can also be said that $S$ generates $M$ (over $R$).

Other terms for $S$ are:
 * A generating set of $M$ (over $R$)
 * A generating system of $M$ (over $R$)

Some sources refer to such an $S$ as a set of generators of $M$ over $R$ but this terminology is misleading, as it can be interpreted to mean that each of the elements of $S$ is itself a generator of $M$ independently of the other elements.
