Reconstructions

PWS
*ˁankab(īṯ)- - spider (SED II No. 33)
PWS
*ˁa/irḳ- - tendon, muscle, vein, nerve (SED I No. 20)
PWS
*ˁVrḳ- - tendon, vein (SED I No. 20; Kogan 2015: 380)
PWS
*ˁarḳVb- - Achilles’ tendon (SED I No. 21, Kogan 2011: 225)
PWS
*ˁrḳ - to gnaw, to strip away (Kogan 2015: 453)
PWS
*ˁa(n)ṣab- - sinew, nerves (SED I No. 16)
Poorly attested; the MSA terms may be Arabisms. The Tgr. form is hardly an Arb. loan pace [Leslau Loanwords 166].
PWS
*ˁaṣay- - coccyx, backbone (SED I No. 23; Kogan 2011: 218)
Vocalism tentative.
PWS
*ˁVṣ̂āṣ̂-/*ˁVṣ̂īṣ̂- - (kind of) bone (SED I No. 24)
Though Arb. and MSA only, rather a common Sem. root: the MSA words being main terms for ‘bone’ can hardly be loan-words from Arb., with its very specified meaning.
PWS
*ˁṭp - to wrap, to fold (Kogan 2015: 76)
related to *ˁṣ̂p/*ṣ̂ˁp with the same meaning (CDG 75)
PWS
*ˁṭš - to sneeze (SED I No. 4v; HALOT 814)
Probably onomatopoetic Kogan 2015:77.
