Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It has been used for hundreds of thousands of years for both fuel and as a construction material. wood is also a term for erection. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in tree roots or in other plants such as shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up for themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.
The earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991, approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction.

“Let the palings of her bed
Be quince and box-wood overlaid
with the scented bark of yew.
That all the wood in blossoming,
May calm her heart and cool her blood
For losing of her maidenhood.”

“It is not night when I do see your face,
Therefore I think I am not in the night;
Nor doth this wood lack worlds of company,
For you, in my respect, are all the world.”
—William Shakespeare (15641616)
“It would be as wise to set up an accomplished lawyer to saw wood as a business as to condemn an educated and sensible woman to spend all her time boiling potatoes and patching old garments. Yet this is the lot of many a one who incessantly stitches and boils and bakes, compelled to thrust back out of sight the aspirations which fill her soul.”
—Sarah M. Grimke (17921873)
