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).

PES
*ṣVgr- - hair (Kogan 2015:449)

Borrowed from Cushitic (Appleyard 1977:17).

PES
*ŝəgā - meat (Dolgopolsky 1973:99, Kogan 2015: 449)
PES
*ṣ̂aḥāy- - sun (Kogan 2015: 446)
PES
*ṣ̂ew - salt (Kogan 2011: 239)

usually thought to be a Cushitism (but cf. Kogan 2006c: 271 for a tentative comparison with Ugr. ṣṣm ‘salt-works’, Hbr. ṣīṣ ‘salt’)

PES
*ṭbw - to suck (Kogan 2011: 228)

is derived from *ṭVb ‘breast’

PES
*ṭirs­ - molar tooth (SED II No. 275)
