Why this word is great
BOOKFELL — [Noun] A prepared animal skin, such as vellum or parchment, used as a writing surface, or the manuscript thus created. From Middle English bocfel ("parchment"), from Old English bōcfell ("parchment, vellum"), a compound of bōc ("book") + fell ("skin, hide"). Unlike vellum, which specifies the fine, calfskin substrate, or paper, which denotes the later technology of pulped plant fibers, bookfell is the blunt, foundational term for the medieval word's physical substance. It is the taut, hairless expanse under the scribe's quill; the faint, pebbled texture of an illuminated capital; the heavy, cool weight of a codex in the lap—the very skin on which thought was once stretched and preserved, a testament that every exalted idea once wore a coat of hair.
