What does sapping mean?
Sapping means weakening something by steadily draining its resources rather than striking it all at once. It is especially associated with the loss of strength, energy, confidence, hope, or morale: prolonged uncertainty can sap confidence, while a demanding schedule can sap a person's energy. Although the verb sounds forceful, its effect is usually gradual, persistent, and difficult to notice until considerable damage has been done. Sapping also has a more specialized literal use for extracting fluid from a plant, particularly by cutting into its trunk. The figurative expression is common in formal and literary English, while the horticultural sense is chiefly technical. Sapping is related to the noun sap, originally the fluid within a tree, and the metaphor developed from the idea that the substance sustaining a plant can be drained away.
To weaken gradually by draining away resources, energy, or strength; also, to extract fluid from a plant.
"Repeated delays sapped their enthusiasm for the project."
The figurative use is literary but established in both British and American English.
Causing or involving gradual weakening or depletion.
"The sapping demands of the job left him exhausted."
This is a participial adjective use, commonly found before words such as strength, energy, or confidence.
Sapping quietly weakens its target, turning a small, steady loss into something far more powerful.

Where does sapping come from?
The word comes from the verb sap, which in its older literal sense referred to cutting into or extracting fluid from a tree. The noun sap derives from Old English sæp, meaning the fluid of a plant. By extension, sap came to symbolize the vital strength or resources of a person or thing, and sapping developed its figurative sense of gradually weakening or exhausting.
