 Definition: 
  1. \Del"ta\, n.; pl. {Deltas}. [Gr. de`lta, the name of the
    fourth letter of the Greek alphabet (the capital form of
    which is [Delta], Eng. D), from the Ph[oe]nician name of the
    corresponding letter. The Greeks called the alluvial deposit
    at the mouth of the Nile, from its shape, the Delta of the
    Nile.]
    A tract of land shaped like the letter delta ([Delta]),
    especially when the land is alluvial and inclosed between two
    or more mouths of a river; as, the delta of the Ganges, of
    the Nile, or of the Mississippi.
    
    
  2. \Del"ta\, n.
    1. The fourth letter of the Greek alphabet ([Delta] [delta]),
       answering to {D}. Hence, an object having the shape of the
       capital [Delta].
    
    2. (Elec.) The closed figure produced by connecting three
       coils or circuits successively, end for end, esp. in a
       three-phase system; -- often used attributively, as delta
       winding, delta connection (which see), etc.

    4. A cobol generating language produced by delta software entwicklung gmbh.

  2. 1. A quantitative change, especially a small or incremental one (this use is general in physics and engineering). "I just doubled the speed of my program!" "What was the delta on program size?" "About 30 percent." (He doubled the speed of his program, but increased its size by only 30 percent.)

    2. [Unix] A diff, especially a diff stored under the set of version-control tools called SCCS (Source Code Control System) or RCS (Revision Control System). See change management.

    3. A small quantity, but not as small as epsilon. The jargon usage of delta and epsilon stems from the traditional use of these letters in mathematics for very small numerical quantities, particularly in "epsilon-delta" proofs in limit theory (as in the differential calculus). The term delta is often used, once epsilon has been mentioned, to mean a quantity that is slightly bigger than epsilon but still very small. "The cost isn't epsilon, but it's delta" means that the cost isn't totally negligible, but it is nevertheless very small. Common constructions include "within delta of ---", "within epsilon of ---": that is, "close to" and "even closer to".
