Originally, Pig Latin was known as Dirty Greek. This is one of the most popular language games of the English language.

CONSONANTS

001.
Method 1: Take the first group or consonants and put them at the end of the word.

Ex.: Snake becomes "ake-sn"

Method 2: Take the very first letter, if it's a consonant, and put it at the end of the word.

Ex.: Snake becomes "nake-s"

002.
Add "ay" or "ey."

Ex.: Snake would be "ake-snay" using method 1. Using method 2, it would be "nake-say."

Please note that the hyphen is not necessary, and adding it makes it easier to decipher. I usually only use it when showing someone how to speak Pig Latin, but leave it out otherwise.

VOWELS

If the word ends with a vowel, add "yay," "way," or "bay." They usually don't mix; e.g. "Ella Anna" would be "Ellayay Annayay," "Ellaway Annaway," or "Ellabay Annabay," but not "Ellayay Annaway."

Another version has it that, no matter the ending, if the beginning of the word has a vowel, then add "yay," "way," or "bay."

Ex.: Amber would become "amberyay" (etc.) in this version. In most versions, "amber" would be "amberay."

A different less popular version has the first letter moved to the end no matter if it's a consonant or a vowel.

Ex.: Elephant would be "lephanteay."

EXTRAS

Compound words are usually split into two words. (Not in all dialects, but in most.)

Ex.: Homework would be split into "home" and "work." Sometimes they're put back together, and sometimes they're not. So homework would be "omehay-orkway."

 
The most popular version is method 1 under "consonants" and the first bit under "vowels." Using that, can you decipher these?
