I am learning about conjugated unsaturated systems, and came upon s-cis and s-trans conformations in conjugated dienes.
So what does the "s" mean in s-cis and s-trans conformations?

The s stands for single, as in single bond. It means the double bonds are cis or trans to each other based around the single bond.
It is a common enough expression to search for, if more information is required.
