Etymology

The word "volume" traces back to Latin volumen, derived from volvere ("to roll"). Ancient books were written on scrolls, which were rolled up—hence the connection to "rolling." Over time, the term expanded to denote the physical size of objects (space occupied) and the intensity of sound (metaphorically "filling space"). The suffix -men (later -me) was used to form nouns indicating the result of an action, giving "volume" its abstract and concrete meanings.
