"OINK" is a small bilingual book of verse written in English and Pig Latin, a made up language many people in the southern United States (Georgia, Alabama, etc) develop and use among friends whenever they wish their conversations to remain private. When a person uses Pig Latin frequently they become very accustomed to it and in essence it becomes another spoken "secret" language. This is a fun little book. Reviews: "Cutest little book I have ever seen and great for all ages."
