*kalbi-

Schürr 2003c, Schürr 2019d:12 explained the name of the river Kalbis (today’s Dalyan Çayı, cf. Tischler 1977a:69, also for philologically untenable etymologies) at Kaunos as ‘deep’, since Strabo (14, 2) called this river deep (which indeed is) and pointed to the Hittite adjective “hallui-”, as well as further similar river names (Καλβιος in Lycia, the spring name Ḫalwannaš in cuneiform sources) that may originate in the same root (in Schürr 2003c:71f. he also included Kalykadnos as a further possible case, see s.v. †ḫallu(wa)ḫḫatar). Although the precise form of the Hittite adjective is ḫallūwa- (cf. HW 2nd ed. Ḫ:84), Schürr’s explanation is both semantically and formally entirely possible as both can be derived from the same stem (on the Carian sound law *Cw > *Cb see Schürr 2003c:71, 2019: 12 and Simon 2008b:460).
