Edwin G. Pulleyblank has suggested that the Wusun, along with the Yuezhi, the Dayuan, the Kangju and the people of Yanqi, could have been Tocharian-speaking. Colin Masica and David Keightley also suggest that the Wusun were Tocharian-speaking. Sinor finds it difficult to include the Wusun within the Tocharian category of Indo-European until further research. J. P. Mallory has suggested that the Wusun contained both Tocharian and Iranian elements. Central Asian scholar Christopher I. Beckwith suggests that the Wusun were Indo-Aryan-speaking. The first syllable of the Wusun royal title Kunmi was probably the royal title while the second syllable referred to the royal family name. Beckwith specifically suggests an Indo-Aryan etymology of the title Kunmi.
