Etymology

Origin of discharge

First recorded in 1300–50; Middle English deschargen, from Anglo-French descharger, Old French, from Late Latin discarricāre, equivalent to dis- dis- ¹ + carricāre “to load”; charge

Explanation

To discharge is to fire a gun or an employee, or to set someone free from a hospital or jail. You'd probably like being discharged from jail, but not from your job, unless you really hate it. As a verb, discharge is “to release,” and as a noun, it refers to the act of or setting free. You'd be discharged from the hospital once the discharge from your wound has stopped. Ew. The writer Ambrose Bierce jokingly defined emotion as "a prostrating disease caused by a determination of the heart to the head. It is sometimes accompanied by a copious discharge of hydrated chloride of sodium from the eyes.” Wouldn't want to cry in front of that guy!
