PES
*nVfās- - wind (Kogan 2015: 456; Kogan 2011: 193)
PES
*plṣ - to divide in two, to split (EDA P E28)
PES
*prd - to separate, to distinguish (between true and false) (EDA P 123)
PES
*pṭr - to shape, to create (EDA I)
PES
*rkb - to meet, to find (LLA 302, CDG 469, Kogan 2015: 457)
PES
*rsˁ - to forget (CDG 474, Kogan 2015: 457)
PES
*sˁm - to kiss (CDG 481; Kogan 2015: 463)

The origin of Proto-EthS *sˁm ‘to kiss’ is unknown. Yemenite Arabic saˁam (Behnstedt 559), correctly identified with the Ethiopian root by W. Müller (apud Leslau), is to be attributed to the contact with an early forerunner of EthS on the Arabian soil.

PES
*sabˀ- - man (Kogan 2015:447)

"The etymology of Proto-EthS *sabˀ is uncertain. One cannot exclude an ultimate connection with Sab. s1bˀ 'to carry out an undertaking, a military campaign', s1bˀt 'expedition, undertaking, journey' (SD 122), Qat. s1bˀ 'to set out, go' (LIQ 157). This comparison would imply an original meaning "gang", "military or working commando." Generalization of the ethnonym s1bˀ 'Saba, Sabaeans' (cf. LLA 359 and Appleyard 1977:8) is also to be seriously considered."

PES
*skm - to carry on shoulders (CDG 496; Kogan 2011: 216)
PES
*ṣbb - to be narrow (CDG 545; Kogan 2015: 464)

The origin of Proto-EthS *ṣbb ‘to be narrow’ is uncertain. Rather problematic are Leslau’s comparisons with Arb. ḍbb ‘to milk by contracting the hand upon the udder’ (Lane 1761), ḍaff- ‘narrow’ (Lane 1794), pB. Hbr. ṣpp ‘to press’ (Jastrow 1297), Syr. ṣappupā ‘numella (tormenti genus)’ (LSyr. 634).
