Morphology

underside = side (transparent) = under + side

The meaning is clearly derived from the prefix 'under' indicating a lower position and the root 'side'.

Etymology

The word underside is made of under 'below' and side 'surface', so it means the bottom or lower surface of something. That's why you check the underside when you look under a table or a leaf.
