In a book lying open in front of you, the verso is the left-hand page and the recto is the right-hand page. In books that read left to right, the verso always carries an even page number and the recto an odd one — which is a quick way to check yourself.

In a book lying open in front of you一本攤開在你面前的書, the verso verso 指的是 is the left-hand page左邊那一頁 and the recto而 recto 是 is the right-hand page右邊那一頁。In books that read left to right在由左向右閱讀的書裡, the verso always carries verso 一定會是 an even page number偶數頁碼 and the recto an odd one而 recto 是奇數頁碼 — which is a quick way to check yourself這是快速確認自己有沒有搞錯的方法。

The word comes from printing and publishing, and it is used by editors, designers, printers and librarians when they need to be exact: 'put the map on the verso, facing the text'. Ordinary readers do not use it; they say 'the left page'.

The word這個字 comes from printing and publishing來自印刷和出版業, and it is used by而是編輯、設計師、印刷師傅和圖書館員 editors, designers, printers and librarians 在需要精確表達 when they need to be exact時使用的字: 'put the map on the verso, facing the text'（例如「把地圖放在 verso，面對正文」）。Ordinary readers一般讀者 do not use it不會用這個字; they say他們會說 'the left page'「左邊那一頁」。

The word has a second, related use with single sheets — a manuscript leaf, a coin, a card. There, the verso is the back side, the side you see after you turn it over, and the recto is the front.

The word這個字 has a second, related use還有第二個相關的用法 with single sheets用在單張的東西上 — a manuscript leaf像手稿的一頁, a coin一枚硬幣, a card一張卡片。There在這個用法裡, the verso verso 是 is the back side背面, the side you see after you turn it over是翻過來之後看到的那一面, and the recto而 recto 是 is the front正面。

That is really the original idea: verso comes from Latin for 'turned', meaning the side showing once the leaf has been turned. Because chapters in printed books usually start on a recto, the verso before a chapter opening is often left blank; you may hear this called a 'blank verso'.

That is really the original idea這其實才是原本的概念: verso comes from Latin for 'turned'verso 來自拉丁文「翻過來」的意思, meaning the side showing once the leaf has been turned指的是紙頁翻過去之後露出來的那一面。Because chapters in printed books usually start on a recto因為印刷書的章節通常從 recto（右頁）開始, the verso before a chapter opening章節開頭前面那一頁 verso is often left blank常常會留白; you may hear this called a 'blank verso'你可能會聽到這被稱為 'blank verso'（空白左頁）。
