self-command

The compound "self-command" is a transparent English formation. The element "self," of ancient Germanic origin, denotes one's own identity or person. "Command" entered English via French from Latin, where its core idea was "to entrust" (commendare), later evolving to mean "to order" or "to control." The logic of the compound is direct: to entrust control to oneself. It embodies the Enlightenment ideal of personal governance, where an individual exercises the authority to master their own impulses and emotions, much as a commander controls troops.

Structure: self (own) + command (control) self: Old English, from Proto-Germanic. A reflexive pronoun meaning "one's own person." command: Middle English, from Old French comander, from Vulgar Latin commandare, from Latin commendare ("to commit, entrust"). The sense of "to order" is from the notion of entrusting orders.
