Source etymology 2

Original entry ↗
verb

To make unstable or infirm; to unsettle; to weaken. · To gradually drain (someone's energy or vitality). · To pierce with saps. · To subvert by digging or wearing away; to mine; to undermine; to destroy the foundation of.

noun

A narrow ditch or trench made from the foremost parallel toward the glacis or covert way of a besieged place by digging under cover of gabions, etc.

Selected source glosses provide context, not a complete modern definition inventory

From French saper (compare Spanish zapar and Italian zappare) from sape (“sort of scythe”), from Late Latin sappa (“sort of mattock”). The sense evolution of from “subvert by digging” to “weaken” was influenced by the sense above “drain wood of sap” as trench warfare receded from public conscience.
