Reconstructions

PS
*ṣ̂Vrˁ- - female breast (SED I No. 274; Kogan 2011: 217)
PS
*ṣ̂irš- - molar tooth (SED I No. 275, Appleyard 1977:17)

Cf. *ṭirs­ - molar tooth. There is no direct parallel to this root in Mesopotamian Akkadian, but ṣiršu ‘protuberance’ and ṣurrušu ‘to grow shoots’ are clearly related to it. If one surmises that the meaning “protuberance” is original, we would be faced with a shared semantic innovation in PWS, but in view of ṣa-ra-sa-tum = ZÚ.GUL in VE 227 and related forms discussed in Krebernik 1983:10 and Conti 1990:101, the opposite possibility, viz. semantic marginalization of an original anatomical term in Babylonian, may appear more attractive. 

PS
*ṣ̂rṭ - to fart, break wind audibly (SED I No. 71ᵥ)
PS
*ŝₓVbay(-at)- - kind of insect (SED II No. 218)
PS
*ŝyb - to have grey hair (SED I No. 66ᵥ)
PS
*ṣ̂yḳ - to be narrow (HALOT 1014; DUL 789; Kogan 2015: 464)
PS
*ṣ̂ayw- - wild cat (SED II No. 224)
Highly uncertain because of the unclear meaning of the Hbr. term.
PS
*tāˀ/y- - kind of antelope (SED II No. 225)
The PS reconstruction is not fully reliable since it is hard to establish the diachronic phonological backround of Hbr. təˀō. One wonders whether -y [-i] in tˀy [tāˀi] in the Samaritan Pentateuch may correspond to -ay in Tgr.
PS
*tiˀin(-at)- - fig, fig tree (Kogan 2012: 254)
P. Fronzaroli suggested *taˀin(-at)- (1969b: 7, 25, 32)
PS
*tbˁ - to set out, to depart (Kogan 2015:342)

Uncertain. Akk.-Ugr. *tbˁ ‘to set out, to depart’ is probably related to Arb. tbˁ ‘to follow’, but the semantic gap underlying this comparison contrasts sharply with the virtual semantic identity between Akkadian and Ugaritc.
