Root Explanation

Coaster originates from the word 'coast' (from Old French *coste*, meaning the side or edge of land) combined with the suffix '-er' (meaning a person or thing that performs a specified action). A coaster is something that is associated with the edge or side, often used to refer to a small mat or holder for drinks to protect surfaces.

Memory Tip

Think of a 'coast' as the edge of land, and remember that a 'coaster' is something that protects surfaces at the edge of your table.
