Skellige jargon is the language used in Skellige. It's based on the Elder Speech of Aen Seidhe elves but has undergone many changes to suit the Islanders. For example, questions are formed by adding "ell'ea" at the end of the sentence, in a manner considered impolite in classical Elder Speech.
During the formative centuries, Skelligers had their own runes
but apparently adopted the  modern alphabet or First Runes at some point later on.

Apart from using altered words of the Elder Speech, based mainly on Celtic languages, Andrzej Sapkowski's language of the Islanders draws heavily from Norwegian and Danish.
In , the language is said to be hard to distinguish from the Wiedźmin: Gra Wyobraźni Nilfgaardian language. This may allude to a minor Dutch influence as the Nilfgaardian is classically full of it.
After being asked by a fan, CD Projekt's narrative designer Mateusz Tomaszkiewicz confirmed Skelligan language used in their games references several different Scandinavian dialects.
 The storytellers at R. Talsorian Games seconded this in by stating that Skelligan names − and by extension the jargon − are generally Scandinavian.
