Reconstructions

PS
*bly - to be old, worn out (CDG 98; Kogan 2015: 184; EDA I 212)

Connection with ESA blyt ‘to be buried suggested by W. Müller (1962: 29, 1963: 307) is doubtful (CDG 98)

PS
*bin- - son (Kogan 2014: 89, Kogan 2015: 398)
Akkadian reflexes of *bin- (binu, bintu and bunu, buntu in AHw. 127, 138) are so marginal that make one suspect a WS import (Kogan 2011: 235).
PS
*bin-(a)t- - daughter (Kogan 2014: 89, Kogan 2015: 398)
PS (Kogan 2014) or PWS (Kogan 2015)?
Akkadian reflexes of *bin- (binu, bintu and bunu, buntu in AHw. 127, 138) are so marginal that make one suspect a WS import (Kogan 2011: 235).
PS
*bVnṯ̣ur- - clitoris, vagina (SED I No. 37, Kogan 2011: 219)
Reliable, though attested only in Akk. and Arb. Note a variety of forms in Arb.
PS
*bny - to build (EDA I 65)
PS
*bar- - kind of bird (SED II No. 61)
PS
*bur- - kind of insect (SED II No. 62)
PS
*burˁ- - reed, mat (EDA I 217)
PS
*brḥ - to be clear (EDA I 233)
PS
*bi/ark- - knee (SED I No. 39)
Cf. *rVk(u)b(­at)­ ‘knee’ (No. 232) and discussion in [GD 163], where separation of these two roots is also favored.
