Let $R$ be a commutative ring with
identity, $I$ an ideal of $R$, and $M$ be an $R$-module. In this paper,
we will introduce the concept of $I$-second submodules of $M$ as a generalization of second submodules of $M$ and obtain some related results.
Keywords: Second submodule; weak second submodule; $I$-prime ideal; $I$-second submodule.
