  Alcohol \Al"co*hol\ ([a^]l"k[-o]*h[o^]l), n. [Cf. F. alcool,
     formerly written alcohol, Sp. alcohol alcohol, antimony,
     galena, OSp. alcofol; all fr. Ar. al-kohl a powder of
     antimony or galena, to paint the eyebrows with. The name was
     afterwards applied, on account of the fineness of this
     powder, to highly rectified spirits, a signification unknown
     in Arabia. The Sp. word has both meanings. Cf. Alquifou.]
     1. An impalpable powder. [Obs.]
        [1913 Webster]
     2. The fluid essence or pure spirit obtained by distillation.
        [Obs.] --Boyle.
        [1913 Webster]
     3. Pure spirit of wine; pure or highly rectified spirit
        (called also ethyl alcohol or ethanol, CH3.CH2.OH);
        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
     Note: [The ferementation is usually carried out by addition
           of brewer's yeast, Saccharomyces cerevisiae to an
           aqueous solution containing carbohydrates.]
           [1913 Webster +PJC]
     Note: As used in the U. S. "Pharmacop[oe]ia," alcohol
           contains 91 per cent by weight of ethyl alcohol and 9
           per cent of water; and diluted alcohol (proof spirit)
           contains 45.5 per cent by weight of ethyl alcohol and
           54.5 per cent of water.
           [1913 Webster]
     4. (Organic Chem.) A class of compounds analogous to vinic
        alcohol in constitution. Chemically speaking, they are
        hydroxides of certain organic radicals; as, the radical
        ethyl+alcohol+({C2H5.OH">ethyl forms common or ethyl alcohol ({C2H5.OH); methyl
        methyl+alcohol+({CH3.OH">forms methyl alcohol ({CH3.OH) or wood alcohol; amyl
        amyl+alcohol+({C5H11.OH">forms amyl alcohol ({C5H11.OH) or fusel oil, etc.
        [1913 Webster]

From The Collaborative International Dictionary of English v.0.48 :

  Amyl alcohol \Am"yl al"co*hol\ (Org. Chem.)
     Any of eight isomeric liquid alcohols ({C5H11.OH),
     transparent, colorless liquids. It is the hydroxide of amyl.
     Also called amylic alcohol. The amyl alcohol obtained from
     fusel oil is mostly isoamyl alcohol (3-methyl-1-butanol or
     1-hydroxy-3-methylbutane), with some sec-amyl alcohol
     (2-methyl-1-butanol or 2-pentanol), and has a
     characteristic peculiar odor. Other than n-amyl alcohol
     (also called 1-pentanol) the other isomeric pentanols are
     not usually refered to as amyl alcohol. The amyl alcohol
     mixture in fusel oil forms a colorless liquid with a peculiar
     cough-exciting odor and burning taste. It is used as a source
     of amyl compounds, such as amyl acetate, amyl nitrite, etc.
     [Webster 1913 Suppl. +PJC]

From WordNet (r) 3.0 (2006) :
