The area or land next to a river.
We had a picnic at the riverside, enjoying the view of the water.
Riverside is formed from "river" (from Old French *riviere*, meaning a flowing body of water) and "side" (from Old English *side*, meaning the lateral part of something). The word "riverside" refers to the area or land that is located at the side of a river.
Think of a 'river' as a flowing body of water and 'side' as the lateral part of something — together, they describe the land next to a river.
