Let R be a commutative ring with nonzero identity, and \(\delta \) an expansion function of its ideals. As a generalization of \(\delta \) -n-ideals, we introduce weakly \(\delta \) -n-ideals which are proper ideals I of R for which, whenever \(0 \ne xy \in I\) for \(x, y \in R\) , it follows that \(x \in \delta (I)\) or y is nilpotent. By exploring various basic properties of weakly \(\delta \) -n-ideals and establishing several characterizations, we reveal the principal symmetries they share with \(\delta \) -n-ideals and related classes such as n-ideals, \(\delta (0)\) -ideals, and \(\delta \) -semiprimary ideals. The transfer of the newly introcued property to ideals of quotient, localization, and product rings is also examined.
