wallet在美式英语中是不是可以指所有钱包？

要了解这个问题，一定要看Wallet的英文定义：

A wallet, or billfold, is a small, flat case that is used to carry personal items such as cash, credit cards, identification documents (driver's license, identification card, club card, etc.), photographs, gift cards, business cards and other paper or laminated cards. Wallets are generally made of leather or fabrics, and they are usually pocket-sized but not always foldable.

wallet(billfold)是一个小而扁平的夹子，用来装现金、信用卡、身份证明文件(驾照、身份证、俱乐部卡等)、照片、礼品卡、名片和其他纸质或层压卡片等个人物品。钱包通常由皮革或织物制成，通常是口袋大小，但并不总是可以折叠。

所以最有可能是用来指图片所指的钱包。
