armory
UK: ˈɑːməri | US: ˈɑːrməri
n. a place where weapons and military equipment are stored
n. a collection of resources or tools for a specific purpose
The word "armory" derives from the Old French armoire (a storage place for arms), which traces back to the Latin armarium (closet or chest for tools/weapons). The root arm- refers to weapons or protective gear, while the suffix -y (or -ery) denotes a place associated with the root. Over time, "armory" evolved to mean both a physical storage space for weapons and metaphorically as a repository of resources.
