pig Latin 的词源

儿童变形语言（有许多不同的版本），到1889年已经出现了（与此类似的hog Latin早在1807年就有记载）。

The animals play quite an important part in the naming [of children's languages], as the hog, dog, fly, goose, pigeon, pig, all give names, with Mr. Hog leading. Among the names the Latins take the lead, and Hog Latin leads the list, being accredited as naming nearly as many languages as all the other names combined. Besides Hog Latin, there is Dog Latin, Pig Latin, Goose Latin, and Bum Latin. Then there is Greekish and Peddlers' French and Pigeon English. ... Very few can give any reason for the naming of the languages. In fact, no one can fully say where the great majority of names came from, for in most cases in the naming the following pretty well expresses the difficulty: "It was born before I was. I can't tell how young I was when I first heard of it." ["The Secret Language of Children," in The North Western Monthly, October 1897]

动物在儿童语言命名中扮演了相当重要的角色，像猪、狗、苍蝇、鹅、鸽子、猪这些动物名都参与其中，其中以“猪”最为突出。在这些名称中，拉丁语（Latins）占据了主导地位，而Hog Latin则名列前茅，被认为命名的语言几乎与其他所有名称加起来一样多。除了Hog Latin，还有Dog Latin、Pig Latin、Goose Latin和Bum Latin。此外，还有Greekish、Peddlers' French和Pigeon English。……很少有人能解释这些语言名称的由来。实际上，没有人能确切说出大多数名称是如何产生的，因为在很多情况下，命名的过程几乎可以用这样一句话来形容：“它在我出生之前就存在了。我无法回忆起我第一次听说它时的年纪。”——摘自《儿童秘密语言》，发表于《西北月刊》，1897年10月

关于这种语言，可以参考loucherbem，这是一种20世纪的法语俚语，类似于猪拉丁语，其名称来源于法语中boucher（屠夫）的变形，据信起源于巴黎的屠夫。此外，还可以比较一下Ziph，这是一种在温彻斯特学院使用的变形语言（德奎西在1859年提到过）。
