verso
/ˈbeɾso/ · B2 · adj
verso, reverse, back, overleaf
📖 verso = a line that TURNS (Latin versus, from vertere 'to turn')
Latin versus meant a turn, a row, then a line of writing, because the plow or the writer turns at line's end. The same idea gives the page's verso: the side you turn over to. Related: reverse, version, converse.
