Verso's counterpart

RECTO

Think of the right-hand page in an open book, often where odd-numbered pages appear in printed works.

"Verso" refers to the left-hand page of an open book, while its counterpart is the right-hand page, called the "recto." The clue plays on printing terminology where these terms describe the two sides of a leaf in a bound book. It’s a straightforward definition with no wordplay—just a direct pairing of opposite terms. If you’ve ever noticed page numbers alternating sides in a book, the odd-numbered ones are usually on the recto.
