UK[ˈkwaɪə]US[ˈkwaɪər]

n
Four sheets of paper folded to form eight leaves, as in medieval manuscripts.
Etymology
The word 'quire' entered English in the 15th century from Anglo-French quayer, which itself evolved from Vulgar Latin quaternus, meaning "set of four sheets." This Latin term derives from quaterni, meaning "four each," a distributive form of quattuor (four). The semantic journey reflects the physical object: from the abstract concept of the number four, to a specific gathering of four folded sheets in bookbinding, and finally generalizing to a standard paper quantity. Its modern definition as a unit of paper measurement directly continues this centuries-old tradition of book production.
Analysis
The word 'quire' is a simplex loanword from Anglo-French, ultimately from Latin. It is not productively formed from smaller, recognizable morphemes in modern English.
Examples
The old manuscript was missing a single quire from its middle section.
We ordered a quire of fine parchment for the calligraphy project.
Traditionally, a ream consists of 20 quires.
