verso

The terms recto and verso refer to the text written on the "front" and "back" sides of a leaf of paper in a bound item such as a codex, book, broadsheet, or pamphlet. The terms are shortened from Latin recto folio and verso folio, translating to "on the right side of the page" and "on the turned side of the page", respectively. The page faces themselves are called folium rectum and folium versum in Latin, and the ablative recto, verso already imply that the text on the page (and not the physical page itself) are referred to.
