Word Origin & History

late 14c., "roll of parchment containing writing, large book," from O.Fr. volume, from L. volumen (gen. voluminis) "roll (as of a manuscript), coil, wreath," from volvere "to turn around, roll" (see vulva). Meaning "book forming part of a set" (1520s) is from a sense in French.
Generalized sense of "bulk, mass, quantity" (1620s) developed from that of "bulk or size of a book" (1520s), again following the sense evolution in the French version of the word.
