[3] Thorkild Jacobsen suggested that the recurring ending -(e)š may have had a grammatical function in Gutian, perhaps as a case marker.

[4] Gutian is included in a list of languages spoken in the region found in the Sag B tablet, an educational text from the Middle Babylonian period possibly originating from the city of Emar.

[6] In a posthumously-published article, W. B. Henning suggested that the different endings of the king names resembled case endings in the Tocharian languages, a branch of Indo-European known from texts found in the Tarim Basin (in the northwest of modern China) dating from the 6th to 8th centuries CE.

He also stated that the Chinese name Yuezhi, referring to nomadic pastoralists living in the grasslands to the northeast of the Tarim in the 2nd century BCE, could be reconstructed as Gu(t)-t'i.

[8] Henning also compared the name of a country called Tukriš, listed with Gutium and other neighbouring countries in an inscription of Hammurabi, with the name twγry found in an Old Turkish manuscript from the early 9th century CE, which is thought to refer to the Tocharians.
