Wood is the xylem tissue of woody plants, notably trees but also shrubs. Wood from the latter is only produced in small sizes, reducing the diversity of uses. Wood is a hygroscopic, cellular and anisotropic material. Dry wood is composed of fibers of cellulose (40%?50%) and hemicellulose (20%?30%) held together by lignin (25%?30%).

Wood has been used by man for millenia for many purposes, being many things to many people. One of its primary uses is as fuel. It may also be used as a material, for making artworks, boats, buildings, furniture, ships, tools, weapons, etc. Wood has been an important construction material since humans began building shelters, and remains in plentiful use today. Construction wood is commonly known as timber in International English, and lumber in American English. Wood may be broken down and be made into chipboard, engineered wood, hardboard, medium-density fibreboard, oriented strand board, paper or used to make other synthetic substances.
