A yard is an area of land immediately adjacent to a building or a group of buildings. It may be either enclosed or open. The word comes from the same linguistic root as the word garden and has many of the same meanings.
A number of derived words exist, usually tied to a particular usage or building type. Some may be archaic or in lesser use now. Examples of such words are: courtyard, barnyard, hopyard, graveyard, churchyard, brickyard, prison yard, railyard, junkyard and stableyard.
The word "yard" came from the Anglo-Saxon geard, compare "garden" (German Garten), Old Norse garðr, Russian gorod = "town" (originally as an "enclosed fortified area"), Latin hortus = "garden" (hence horticulture and orchard), from Greek χορτος (hortos) = "farm-yard", "feeding-place", "fodder", (from which "hay" originally as grown in an enclosed field). "Girdle," and "court" are other related words from the same root.
In areas where farming is an important part of life, a yard is also a piece of enclosed land for farm animals or other agricultural purpose, often referred to as a cattleyard, sheepyard, stockyard, etc. In Australia portable or mobile yards are sets of transportable steel panels used to build temporary stockyards.
The yard (abbreviation: yd) is an English unit of length, in both the British imperial and US customary systems of measurement, that comprises 3 feet or 36 inches. It is by international agreement in 1959 standardized as exactly 0.9144 meters. A metal yardstick originally formed the physical standard from which all other units of length were officially derived in both English systems.
In the 19th and 20th centuries, increasingly powerful microscopes and scientific measurement detected variation in these prototype yards which became significant as technology improved. In 1959, the United States, United Kingdom, Australia, New Zealand, and South Africa agreed to adopt the Canadian compromise value of 0.9144 meters per yard.
The term yard is also sometimes used for translating related lengths in other systems.
The name derives from the Old English gerd, gyrd, &c., which was used for branches, staves, and measuring rods. It is first attested in the late-7th century laws of Ine of Wessex, where the "yard of land" mentioned is the yardland, an old English unit of tax assessment equal to 1⁄4 hide. Around the same time, the Lindisfarne Gospel's account of the messengers from John the Baptist in the Book of Matthew used it for a branch swayed by the wind. In addition to the yardland, Old and Middle English both used their forms of "yard" to denote the surveying lengths of 15 or 16 1⁄2 ft used in computing acres, a distance now usually known as the "rod".
Land, sometimes referred to as dry land, is the solid surface of the Earth that is not permanently covered by water. The vast majority of human activity occurs in land areas that support agriculture, habitat, and various natural resources.
Some life forms (including terrestrial plants and terrestrial animals) have developed from predecessor species that lived in bodies of water.
Areas where land meets large bodies of water are called coastal zones. The division between land and water is a fundamental concept to humans. The demarcation between land and water can vary by local jurisdiction and other factors. A maritime boundary is one example of a political demarcation. A variety of natural boundaries exist to help clearly define where water meets land. Solid rock landforms are easier to demarcate than marshy or swampy boundaries, where there is no clear point at which the land ends and a body of water has begun. Demarcation can further vary due to tides and weather.
