Words

Ugaritic
ˀarkd - a projectile (DUL 103, Watson 2007: 78)

meaning highly uncertain, a borrowing from Akk. ariktu ‘spear’ is unprovable and, in view of -d, rather unlikely (Kogan 2015: 360).

Ugaritic
ˀirn - puppy, puppy-dog (DUL 104, differently Watson 2007: 78)
Semantically rather uncertain, a connection with either Akk. urnu ‘a snake’ or Akk. mīrānu ‘young dog, puppy’ is not to be ruled out (cf. SED II No.8), but there is no reason to assume an Akkadian loanword in any of the two cases (Kogan 2015: 360). The word is extensively discussed in Aartun 1983. Cf. also DRS 26.
Ugaritic
ˀarṣ - earth (DUL 107)
Ugaritic
ˀirt - breast (DUL 110)
Ugaritic
ˀart - shield (DUL 109)
meaning uncertain, borrowing from Akk. arītu ‘shield’ is purely conjectural (contra Watson 2007: 78) (Kogan 2015: 360).
Ugaritic
ˀarw - lion (DUL 111)
Ugaritic
ˀarz - cedar (DUL 113–14; Watson 2004: 113)
Ugaritic
ˀasr - prisoner, captive (DUL 114, Watson 2007: 79)
Since *ˀasīr- ‘prisoner’ is widely attested in WS, whereas Akk. asīru is probably an early WS loanword (Kogan2008b:105 and 110, with references), there is hardly an reason to postulate an Akkadian loanword in Ugaritic (Kogan 2015: 356).
Ugaritic
ˀuṣbˁ - finger (DLU 55)
Ugaritic
ˀišd - leg (DUL 116, Watson 2007: 79)
cf. Akk. ˀišdu (Kogan 2015: 332)
it is debatable whether the word is related to PWS *šit- ‘buttocks’, see Kogan 2011: 218
