Akk.-Ugr. isogloss
The etymology of Ugr.-Akk. *ḫarrān- ‘road, caravan, gang’ is unknown. J. Huehnergard’s comparison with Arb. ḥrr (II) ‘to set free; to point, to adjust’ (Huehnergard 2003:105, 116) is not very appealing from the semantic point of view, the more so since the meaning “to set free” is obviously derived from ḥrr (I) ‘to be free,’ ḥurr- ‘freeborn’ (Lane 538), with transparent cognates throughout CS (HALOT 348, Kogan 2015:211). Semantically more suitable could be Gez. ḥarā ‘army, troops’ (CDG 240), usually derived from the same root *ḥrr ‘to be free’ (Kogan 2015:335).
