  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.
