• Obtained descriptions for weakly injective and weakly projective Abelian groups.
• Examined related classes of Abelian groups to strengthen the understanding of their connections.
• Provided detailed descriptions of weakly injective and weakly projective modules.
• Established relationships among weakly injective, weakly projective, and other classes of Abelian groups.
• Highlighted significant connections to quasi-injective and quasi-projective modules.
