What does armory mean?
An armory is, most literally, a place where weapons and military equipment are kept — a storehouse of arms maintained by a state, a garrison, or a military unit. In the United States, the word also commonly refers to the drill halls and meeting buildings of National Guard units, many of which are imposing civic structures in towns across the country. Beyond its military sense, armory has developed a well-established figurative use: a person's 'armory' may consist of arguments, skills, or resources they can draw upon, as in 'an armory of persuasive techniques.' The word derives from the same Latin root as 'armor' and 'armament,' reflecting its martial origins. In American spelling it appears as armory, while British English uses armoury. Whether describing a physical depot or a metaphorical stockpile of capabilities, the word conveys readiness, accumulation, and preparedness.
nounA place where weapons and military equipment are stored, or a building used by a military unit such as the National Guard for drills and storage. It can also refer to an entire stockpile or array of available resources or tools.
- A building or place where weapons and military equipment are stored.
- A building used by a military unit, especially a National Guard or militia unit, for drills, meetings, and equipment storage.
- A complete stockpile or repertoire of resources, skills, or tools available for use (figurative).
"The National Guard unit assembled at the armory before deploying to assist with flood relief."
"Soldiers reported to the armory at dawn to collect their gear before the exercise."
"The negotiator brought an impressive armory of rhetorical techniques to the debate."
The standard American plural is 'armories'; British English spells both singular and plural with a 'u' ('armoury', 'armouries').
"Across the state, decommissioned armories have been converted into gyms, shelters, and event venues."
New York's famous 1913 Armory Show wasn't about weapons at all — it was held in an armory building and introduced America to modern art, scandalizing critics with works by Duchamp and Matisse.

Etymology of armory
Armory comes from the Old French 'armoire' or 'armure,' ultimately rooted in the Latin 'arma,' meaning arms or weapons — the same root that gives us armor, armament, armada, and armistice. The word entered Middle English in the medieval period, when it denoted a storehouse for weapons and armor. Its spelling diverged over time, with American English settling on 'armory' and British English on 'armoury.' The figurative sense of a stockpile of non-military resources developed later, extending the original idea of a repository of arms to repositories of skill and argument.

In American English the spelling is 'armory'; British English uses 'armoury'. The figurative sense — an 'armory' of skills, arguments, or tools — is common in journalism and formal writing. The word carries a slightly martial, institutional connotation even when used figuratively.
