noun
quire
KWIRE/ˈkwaɪər/
A set of paper sheets forming a single unit.
The paper sheets form a single quire arranged in five small fans.

Etymology
Quaternum named a set of four sheets of parchment or paper. The English word became a standard unit for selling paper, so its usual count of twenty-four or twenty-five no longer reflects the original four.
