An endomorphism of an abelian variety is a morphism from the variety to itself. The set of endomorphisms of an abelian variety $A$ form a ring in which addition is defined point-wise (using the group operation of $A$) and multiplication is composition; this is the endomorphism ring of $A$, denoted $\textrm{End}(A)$.
