Word Origin and History for sapping

sap

n.

"liquid in a plant," Old English sæpm from Proto-Germanic *sapam (cf. Middle Low German, Middle Dutch, Dutch sap, Old High German saf, German Saft "juice"), from PIE *sab- "juice, fluid" (cf. Latin sapere "to taste"), from root *sab- "juice, fluid" (cf. Sanskrit sabar- "sap, milk, nectar," Irish sug, Russian soku "sap," Lithuanian sakas "tree-gum"). As a verb meaning "To drain the sap from," 1725.

"simpleton," 1815, originally especially in Scottish and English schoolboy slang, probably from earlier sapskull (1735), saphead (1798), from sap as a shortened form of sapwood "soft wood between the inner bark and the heartwood" (late 14c.), from sap (n.1) + wood (n.); so called because it conducts the sap; cf. sappy.

"club, stick for hitting," 1899, from shortening of sapwood (see sap (n.2)) or sapling.

v.

"dig a trench toward the enemy's position," 1590s, from Middle French saper, from sappe "spade," from Late Latin sappa "spade" (cf. Italian zappa, Spanish zapa "spade"). Extended sense "weaken or destroy insidiously" is from 1755, probably influenced by the verb form of sap (n.1), on the notion of "draining the vital sap from." Related: Sapped; sapping.

"hit with a sap," 1926, from sap (n.3). Related: Sapped; sapping.

Encyclopedia Article for sapping

sap

watery fluid of plants. Cell sap is a fluid found in the vacuoles (small cavities) of the living cell; it contains variable amounts of food and waste materials, inorganic salts, and nitrogenous compounds. Xylem sap carries soil nutrients (e.g., dissolved minerals) from the root system to the leaves; the water is then lost through transpiration. Maple sap is xylem sap, containing some sugar in late winter. Phloem, or sieve-tube, sap is the fluid carrying sugar from leaves to other parts of the plant in the summer.
