delta

delta
    n 1: a low triangular area of alluvial deposits where a river
         divides before entering a larger body of water; "the
         Mississippi River delta"; "the Nile delta"
    2: an object shaped like an equilateral triangle
    3: the 4th letter of the Greek alphabet
    

Delta \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.]
   1. The fourth letter of the Greek alphabet ([Delta] [delta]),
      corresponding to {D}. Hence, an object having the shape of
      the capital [Delta].
      [Webster 1913 Suppl.]

   2. 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.
      [1913 Webster]

   3. (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.
      [Webster 1913 Suppl.]
    

delta
 n.

   1. [techspeak] 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).

   3. n. 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'.
