PWS biconsonantal element

PWS
*hdˀ - to be quiet (Kogan 2015: 221 note 663)

Sparcely attested, the PS reconstruction is not fully reliable.
PWS
*ḥadr-/*ḫadr- - inner room, living quarters (Kogan 2015: 82)
*ḫ in Arabic, ESA, EthS and MSA vs. *ḥ in Ugaritic and Ebla. Perhaps also Soq. ḥdr ‘s’arrêter’ (LS 165), attested in Müller 1905:287 (ḥedaíroh ‘sie ließ sich nieder’)
PWS
*ḥaḏVy- - breast (SED I No. 112)
Note likely related forms, with different shifts of meaning, in various Sem. languages (Arb., ESA: Min., Eth.: Gez., Amh.)
PWS
*ḥgl - to bind; to encircle (CDG 228)
PWS
*ḥagal- - partridge (SED II No. 97)
The Common Semitic status of this root is uncertain since inter-Semitic borrowing are possible. Whereas an Arabism in Syriac is not very likely (the Syr. term is attested already in the Peshitta), an Arb. borrowing in Tgr. is quite probable.
PWS
*ḥVḳw- - back, loin, hip (SED I No. 113; Kogan 2011: 218)
