What does delegacy mean?
"Delegacy" is a formal noun with two related senses: it denotes the act of delegating — that is, conferring authority, power, or responsibility upon another person or body — and, less commonly, the group of delegates itself, a deputation chosen to act on behalf of others. The word derives from Latin delegare, "to send away or assign," the same root that gives us "delegate" and "delegation." Today it survives chiefly in legal, constitutional, and parliamentary contexts, where precision about who holds transferred authority matters; in ordinary speech, "delegation" serves both meanings and is far more common. A writer might say that a statute operates "by delegacy" of legislative power to an agency, or that a delegacy was sent to negotiate on a city's behalf. Though rare, the word carries an air of institutional formality and historical weight, making it useful when the tone demands gravity rather than everyday plainness.
The act or process of delegating authority, power, or responsibility to another person or body.
"The statute's effectiveness depends on the careful delegacy of regulatory power to the agency."
Chiefly legal and administrative; "delegation" is preferred in general usage.
A body of delegates; a deputation appointed to represent others.
"A delegacy from the trade union presented its grievances at the ministry."
Now rare; largely superseded by "delegation" or "deputation."
Regular plural; used when referring to multiple acts of delegation or multiple bodies of delegates.
"The constitution permits various delegacies of executive authority to subordinate offices."
Before "delegation" took over, English speakers handed off power by "delegacy" — a Latinate rarity that still survives in legal and parliamentary prose.

Etymology of delegacy
"Delegacy" comes from Latin delegare, meaning "to send away, dispatch, or assign to another," formed from de- ("away") plus legare ("to send with a commission"). It entered English in the early modern period, around the seventeenth century, alongside its sibling words "delegate" and "delegation." Its Romance cognates include French délégation and Spanish delegación, all traceable to the same Latin root that also yields "legate" and "relegate."
How delegacy is actually used
Formal and rare; found chiefly in legal, constitutional, and parliamentary writing. In everyday usage, "delegation" has almost entirely displaced it in both senses.
Easily confused with delegacy
"Delegation" is the standard, everyday word for both the act of entrusting tasks and the group of delegates, while "delegacy" is a rare, formal synonym used chiefly in legal and parliamentary contexts.
