Areal reconstruction
*baḥr- - sea (Fronzaroli 1968: 273, 288, 299; Kogan 2011: 191)
Areal reconstruction
*bāb- - door, gate (EDA I 58)

Borrowed from Akkadian (often via Aramaic and Arabic) into a wide range of Semitic languages. The origin of the Akkadian lexeme is uncertain. 

Areal reconstruction
*badan- - body, trunk (SED I No. 31; Kogan 2011: 214)
Areal reconstruction
*bdˀ - to make for the first time, to begin (Kogan 2015:550)
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
*buṣ- - byssus (EDA I 398)
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
*dhr - to go around (DRS 230, EDA II)

A variant root to PS *dwr. At least some of the MSA lexemes may be borrowed from Arabic.

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