fourth letter of the Greek alphabet (the capital form of

corresponding letter. The Greeks called the alluvial deposit
at the mouth of the Nile, from its shape, the Delta of the
Nile.]

corresponding to D. Hence, an object having the shape of
the capital [Delta].
[Webster 1913 Suppl.]

especially when the land is alluvial and inclosed between
two or more mouths of a river; as, the delta of the

coils or circuits successively, end for end, esp. in a

The Jargon File (version 4.4.7, 29 Dec 2003):
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?.
