Ilgar, also known as Garig-Ilgar after its two dialects, is an extinct Iwaidjan language spoken in the mainland of Cobourg Peninsula, around Port Essington, Northern Territory.
[2] Unlike many Australian languages, Ilgar does not have lamino-alveolars.
Evans (1998) briefly discusses vowels in his paper noting that Iwaidjan languages including Ilgar have a three vowel (/a/, /i/, /u/) system typical of most Australian languages.
