My whole family speaks Pig Latin and in Jr. High I actually did a a report in english class about the origins of it. After speaking to many people I found out that Pig Latin came about during the flower child period. Hippies created this alternet way of speaking english so that they could speak freely to eachother when they got arrested. The actual name came about because the "pigs" did not understand them, thus Pig Latin. As to the response left before mine it is half way true, you take the frist letter(s) up to the first vowel move it/them to the end and add ay. However there are a few exceptions to this if the frist letter is a vowel you take that letters off up to the second vowel and add an ay then remove take the letters after it and add an ay. If there is no second vowel just add ay to the end of the word. Also if the word is only a vowel just add an ay. Examples: applay eay (apple), anday (and), Iay (I). If you have a long word you may have to split it up the best way to explain this is just to give you an example. Example: Ihay erbay atenay (Hibernate). I hope this answered your question and I am happy to share my useless knowledge with you.
