Wad

Wad is an old mining term for any black manganese oxide or hydroxide mineral-rich rock in the oxidized zone of various ore deposits. Typically closely associated with various iron oxides. Specific mineral varieties include pyrolusite, lithiophorite, nsutite, takanelite and vernadite. Wad can be considered to be the manganese equivalent to the iron mineraloid limonite.

Doom WAD

Doom WAD is the default format of package files for the video game Doom and its sequel Doom II: Hell on Earth, that contain sprites, levels, and game data. WAD stands for Where's All the Data?. Immediately after its release in 1993, Doom attracted a sizeable following of players who created their own mods for WAD files—packages containing levels, graphics, and other game data—and played a vital part in spawning the mod-making culture which is now commonplace for first-person shooters. Thousands of WADs have been created for Doom, ranging from single custom levels to full original games; most of these can be freely downloaded over the Internet. Several WADs have also been released commercially, and for some people the WAD-making hobby became a gateway to a professional career as a level designer.

There are two types of WADs: IWADs (internal WADs) and PWADs (patch WADs). IWADs contain the data necessary to load the game, while PWADs contain additional data, such as new character sprites, as necessary for custom levels.

Wood (surname)

Wood is a surname in the English language. It is common throughout the world, especially countries with historical links to Great Britain and Germany.

Etymology

For the most part, the surname Wood originated as a topographic name used to describe a person who lived in, or worked in a wood or forest. This name is derived from the Middle English wode, meaning "wood" (from the Old English wudu). An early occurrence of this surname (of a personal residing near a wood) is de la Wode, recorded in Hertfordshire, England, in 1242. The locational name also appeared in early records Latinised as de Bosco (from the Old French bois, meaning "wood"). Another derivation for the surname is from a nickname of an eccentric or violent person, derived from the Old English wōd,wad, and Middle English wod, wode, all meaning "frenzied" or "wild". This derivation is considered to be much less common than the locational origin. An early occurrence of the surname derived in this fashion (from a nickname) is le Wode, recorded in Worcestershire, England, in 1221.
