Pig Latin
Pig Latin is a language game or cant in which words are altered by adding a fabricated suffix or by moving the onset or initial consonant or consonant cluster of a word to the end of the word and adding a vocalic syllable (usually -ay or /eɪ/) to create such a suffix. For example, in English, "he does not know" would become "ehay oesday otnay owknay".
The objective is often to conceal the words from others not familiar with the rules. The reference to Latin is a deliberate misnomer; Pig Latin is simply a form of argot or jargon unrelated to Latin, and the name is used for its English connotations as a strange and foreign-sounding language. It is most often used by young children as a fun way to confuse people unfamiliar with Pig Latin, such as adults.
Pig Latin exists in various languages across the world.
