Spoon language is the name given to a secret or play language. The spoon language is based on the exchange of the vowels of a word by fixed abbreviations, whereby the consonants of the word remain untouched.
It is unclear where the term actually originated. However, it expresses very onomatopoeically what the game language is all about. It is based on a rather high density of the letter l, since vowels as well as diphtongs are replaced by a combination of the original letter and an l. All other letters of the alphabet remain untouched.
