Words

Ugaritic
ss̀t - baseboard, floor of a chariot (DUL 772, Watson 2007: 106)
uncertain, borrowing from Akk. sassu (CAD S 195) or any of the alternative Akkadian parallels mentioned by Watson is unprovable
Ugaritic
ssw - horse (DUL 772)

Var. s̀s̀w. Cf. sswt ‘mare’. Of uncertain origin (cf. SED II No. 199), but, contra Watson 2007: 70, certainly not an Akkadism in Ugaritic (Kogan 2015: 359).

Ugaritic
š - ram, sheep (DUL 794)
Ugaritic
šˀb - to draw water (DUL 794)
Ugaritic
šˀir - flesh (DUL 797)
Ugaritic
šˀiy - raptor (Watson 2007: 107, cf. DUL 798)
quite uncertain (cf. Pardee 1997: 350), but even if ša-a-i ‘falcon, hawk’ in the Emar lexical list (Pentiuc 2001: 165) is thought to be related, it is by no means certain that the Emar word belongs to the Akkadian rather than local WS lexical stratum.
Ugaritic
šˀl - to ask, request (DUL 795)
Ugaritic
šˀn - shoe, sandal(s); rim (?) (DUL 758)
Ugaritic
šˁr - barley (DUL 798)
