What does discharge mean?
Discharge functions as both a noun and a verb, centered on the idea of release or unburdening. As a verb, it means to dismiss someone from a hospital, job, or military service; to unload goods from a vessel; to emit a substance such as fluid or electricity; or to fulfill a duty or obligation. As a noun, it denotes the act of such release, the material discharged, or official documentation of dismissal, as in an honorable discharge from the armed forces. The word carries no strong emotional connotation on its own but appears most often in formal, institutional, medical, legal, and scientific settings. Its versatility across these domains makes it a valuable term for precise communication about obligations ended, burdens lifted, or substances released.
To release someone from a place, duty, or obligation; to unload or emit something; to fulfill a duty.
"The ship will discharge its cargo at dawn."
In legal contexts, often used for settling debts or performing obligations.
An act of releasing, unloading, or emitting; the substance emitted; or official documentation of release from service.

Discharge literally traces back to 'unloading a cart' — every time you're discharged from hospital, you're linguistically being taken off the wagon.

Etymology of discharge
Discharge derives from Old French 'deschargier,' meaning to unload, formed from 'des-' (expressing reversal) plus 'chargier' (to load), which itself comes from Late Latin 'carricare,' to load a cart, from Latin 'carrus,' a wheeled vehicle. It entered English in the Middle Ages, initially referring to unloading ships or relieving burdens. Cognates include 'charge,' 'cargo,' and 'chariot,' all tracing back to the same Latin root for cart or wagon.
