Pig-Latin
Most words in Pig Latin end in "ay." Use the rules below to translate normal English into Pig Latin.

1. If a word starts with a constant and a vowel, put the last letter of the word at the beginning of the word and add "ay."
Example: Happy = Yhappy + ay = Yhappay

2. If a word starts with two constants move the two constants to the end of the word and add "ay."
Example: Child = Ildch + ay = Ildchay

3. If a word starts with a vowel add the word "way" at the end of the word.
Example: Awesome = Awesome +way = Awesomeway

The sentence "Pig Latin is hard to speak." is written below in Pig Latin:
Gpiay Nlatiay isway dharay otay eakspay.

Notice how "Gpiay" is actually "Pig." Because the last character of pig is moved to the front, with "ay" added to the end, it makes Pig Latin very hard to read.

Decoding Pig Latin
Because Pig Latin is a method for translating words of the English language into a different language one can make up a code book for each commonly used word.
