Webster's 1913 Dictionary
 
 Definition: 
\Ab*strac"tion\, n. [Cf. F. abstraction. See
{Abstract}, a.]
1. The act of abstracting, separating, or withdrawing, or the
   state of being withdrawn; withdrawal.

         A wrongful abstraction of wealth from certain
         members of the community.             --J. S. Mill.

2. (Metaph.) The act process of leaving out of consideration
   one or more properties of a complex object so as to attend
   to others; analysis. Thus, when the mind considers the
   form of a tree by itself, or the color of the leaves as
   separate from their size or figure, the act is called
   abstraction. So, also, when it considers whiteness,
   softness, virtue, existence, as separate from any
   particular objects.

Note: Abstraction is necessary to classification, by which
      things are arranged in genera and species. We separate
      in idea the qualities of certain objects, which are of
      the same kind, from others which are different, in
      each, and arrange the objects having the same
      properties in a class, or collected body.

            Abstraction is no positive act: it is simply the
            negative of attention.             --Sir W.
                                               Hamilton.

3. An idea or notion of an abstract, or theoretical nature;
   as, to fight for mere abstractions.

4. A separation from worldly objects; a recluse life; as, a
   hermit's abstraction.

5. Absence or absorption of mind; inattention to present
   objects.

6. The taking surreptitiously for one's own use part of the
   property of another; purloining. [Modern]

7. (Chem.) A separation of volatile parts by the act of
   distillation. --Nicholson.

 
Computing Dictionary
 
 Definition: 

1. Generalisation; ignoring or hiding details to capture some kind of commonality between different instances. Examples are abstract data types (the representation details are hidden), abstract syntax (the details of the concrete syntax are ignored), abstract interpretation (details are ignored to analyse specific properties).

2. Parameterisation, making something a function of something else. Examples are lambda abstractions (making a term into a function of some variable), higher-order functions (parameters are functions), bracket abstraction (making a term into a function of a variable).

Opposite of concretisation.
