Antapa is a fictional language which is associated with the con-nation of Qiní. It was created by Jan Havliš in 1999, and used in his (unpublished?) novel "Höw Nehhinaäf" (Song about the Nothern Star). It started out as a funlang, but developed further after Havliš began writing his book.
The language is influenced by Hebrew and Arabic, but rather than using a consonantal root system, the author has elected for a vowel-based one.
