"sheet of paper," 1589 (earlier
pagne, 12c., directly from O.Fr.), from M.Fr.
page, from O.Fr.
pagine, from L.
pagina "page, strip of papyrus fastened to others," related to
pagella "small page," from
pangere "to fasten," from PIE base
*pag- "to fix" (see
pact). Usually said to be from the notion of individual sheets of paper "fastened" into a book. Ayto offers an alternate theory: vines fastened by stakes and formed into a trellis, which led to sense of "columns of writing on a scroll." When books replaced scrolls, the word continued to be used.
Page-turner "book that one can't put down" is from 1974.
