Hurrian

Evidence about the Hurrian language is scarce and indirect, thus possibly leading to many false assumptions and conclusions.

𒄷𒌨𒊑 Ḫu-ur-ri Hurrian also called Hari, Khurrites, Hourri, Churri, Hurri or Hurriter <> Kassite

The largest and most influential Hurrian nation was the kingdom of Mitanni, its ruling class perhaps being Indo-Iranian speakers.

Urartian is closely related to Hurrian

Some argue for it to be part of the PIE language family.

Urartian was also rarely written in the "Anatolian hieroglyphs" used for the Luwian language.

Commenting on this:

A first set of phonemes is richly documented  : *H4, *bh, *dh, *ğh, *H1, *H2, *l, *m, *n, *H3, *p, *s, *w. These phonemes belong to the voiced aspirated, laryngeal and resonant series. They represent the phonological core of PIE. It is unclear if word-initial *st should be considered a phoneme on its own.  
- A second set seems to be fairly rare: *gw, *gh, *ghw, *y, *kw.  

The reason that gw, *gh, *ghw, *y, *kw are rare is that they are identical with one of H1 H2 H3 / *ğ, *g, *gw. the voiceless phonemes *ǩ, *k, *t do not seem to combine with laryngeals

PIE *H4ebh-, *H4ew- ‘some kind of oat or grass seed’
IEW *awiğ- ‘Hafer’ *Haewis ‘oats’ Heu Latin avēna ‘oat’:

PIE *H4el- ‘other’ (a well-established root) alternate alas else:
IEW 24–26 *al-: *alyos ‘anderer’, Mallory–Adams 485 *Haélyos ‘other’ Hurrian alaše ‘(if) otherwise’ (BGH 16)
Hurrian and Urartian uli ‘other’ (BGH 484) (ul- < zero-grade)
Hurrian ullui ‘on the other hand’ (BGH 488)
According to Hurrian, the laryngeal is *H4.
