(n.)
Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation.
  
(n.)
An impalpable powder.
  
(n.)
A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5.OH); methyl forms methyl alcohol (CH3.OH) or wood spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.

Alcohol
In chemistry, an alcohol is any organic compound in which a hydroxyl group (-OH) is bound to a carbon atom of an alkyl or substituted alkyl group. The general formula for a simple acyclic alcohol is CnH2n+1OH.

In layman's terms, the word alcohol (, "al-kuḥl") usually refers to ethanol, also known as grain alcohol or (older) spirits of wine, or to any alcoholic beverage. Ethanol is a colorless, volatile liquid with a mild odor which can be obtained by the fermentation of sugars. (Industrially, it is more commonly obtained by ethylene hydration — the reaction of  ethylene with water in the presence of phosphoric acid.) Ethanol is the most widely used depressant in the world, and has been for thousands of years. This sense underlies the term alcoholism (addiction to alcohol).
