Reconstructions

PS
*ŝalāṯ- - three (Kogan 2009: 72)
PS
*ŝVm- - kind of mouse, rat (SED II No. 214)
Not very reliable since ŠU in the Eblaite form points to ṯ rather than *ŝ or *š in the protoform which is not compatible with š in Arb.
PS
*ŝₓV̄m-at- - birth-mark, mole

An entangled and highly hypothetic case likely complicated by contamination of two roots, close phonetically and semantically. In the anatomic term, a hypothetic *ŝx is tentatively postulated as a first radical based on Hbr. pB. š-­ and Arb. š-­.

PS
*ŝamˀāl- - left hand (side) (SED I No. 264; Kogan 2011: 197)
PS
*ŝmḫ - to be high, tall (Kogan 2015: 307)
PS
*ŝamš- - sun (HALOT 1589; Fronzaroli 1965a: 137, 144, 149; Kogan 2011: 192–193; Kogan 2015: 35)
PS
*ŝVp- - tuft of hair (SED I 259, Kogan 2015: 539)
PS
*ŝVp(V)r- - eyelash; (tuft of) hair (SED I No. 266)
Though widely represented, not quite reliable because of considerable difference of meaning in individual languages and phonetic irregularities in Hbr. and Akk.
PS
*ŝrb - to sip, to absorb (Fronzaroli 1971: 607, 630, 638–639; Kogan 2011: 238)
Level?
