What does decking mean?
Decking refers to the boards or planks used to build the flat surface of a deck, particularly the weatherproof timber laid over a supporting frame to form an outdoor floor in gardens and patios. As a mass noun, it names the material rather than the finished structure: a homeowner might order decking, lay decking, or choose between softwood, hardwood, or composite decking. The word derives from "deck," which entered English from Middle Dutch via nautical use, describing the planked floors of ships; over time the term extended to land-based structures, so decking can also describe the planked surfaces of roofs, bridges, and other platforms. Today it is strongly associated with home improvement and outdoor living, evoking leisurely spaces for dining and entertaining. Because different materials vary greatly in cost and durability, decking is also a common subject of practical discussion among builders and gardeners alike.

Etymology of decking
The noun "decking" is formed from "deck," which entered English in the sixteenth century from the Middle Dutch "dec," meaning the floor or covering of a ship. Originally a purely nautical term for a ship's planked floors, "deck" was later extended to any raised flat platform, and "decking" came to denote the boards or planks making up such a surface. Its modern prominence in the sense of garden flooring reflects twentieth-century growth in outdoor home improvement, especially in Britain and North America.
