Reconstructions

Proto-MSA
*wzm - to give; to lend (Kogan 2015:576)

"Must be related to Arab. wzm 'to pay a debt; to join a small piece of something to what is similar to it" (LA 12 756), so sparsely attested that one may wonder whether it is autochtonous in Arabic. A borrowing from Arabic into MSA is, in this case, quite unlikely" (Kogan 2015:576)

Proto-MSA
*ydn - to be new (Kogan 2015: 33, ibid. 527)
Proto-MSA
šitim- - heaven (Kogan 2015: 571)

The origin of Proto-MSA *šitim- ‘heaven’ is enigmatic: an eventual connection with PS *šamāy- is difficult to avoid (Bittner 1909:42), but the underlying phonological and/or structural development has never been convincingly established (none of the hypotheses listed by Leslau in LS 78 is persuasive).

Areal reconstruction
*ˀibil- - camel (SED II No. 2, Kogan 2011: 207)

one of the four widespread designations of camel in individual languages, the similarity between these designations must be due to diffusion from an Arabian source

Areal reconstruction
*baḥr- - sea (Fronzaroli 1968: 273, 288, 299; Kogan 2011: 191)
Areal reconstruction
*badan- - body, trunk (SED I No. 31; Kogan 2011: 214)
Areal reconstruction
*bVkr- - camel (SED II No. 56, Kogan 2011: 207)

one of the four main designations of camel in individual languages, the similarity of these designations must be due to diffusion from an Arabian source

Areal reconstruction
*baḳl-, *baγl- - mule (SED II No. 55; Kogan 2011: 206–207)
Areal reconstruction
*būḥ- - phallus; genitalia (SED I No. 35)

Very scarce attestation: Arb. and ESA only; possibility of an inter-borrowing cannot be ruled out. Seems to be supported by Afras.

Areal reconstruction
*duḫn- - millet (Fronzaroli 1969b, pp. 13, 28, Kogan 2012: 247)
