means One side of a sheet of paper in a book, document, or website — the basic unit on which text and images are laid out.

from From Latin 'pagina,' meaning a written page or column of writing, which sprang from the root 'pangere,' 'to fasten' or 'fix in place.' The image is agricultural and practical: Romans pictured rows of vines fastened to trellises, and a 'pagina' was that orderly arrangement of lines fixed onto papyrus — the eye walking neat rows like a vineyard. It reached English through Old French 'page.' (The 'page' who fetches and carries is a different word entirely, from Italian 'paggio,' so don't let them share a trellis.)
