Reconstructions

PS
*ˁaw/yš-, *ˁašw/y- - kind of disease (fever, cold in the head; plague) (SED I No. 27)
The Akk. variant form with ḫ- may also suggest γ-. The ESA and Jib. forms, however, clearly point to ˁ-.
PS
*ˁayn- - eye (SED I No. 28)
reflexes are applied throughout Semitic to designate ‘spring’ as source of water, s. Kogan 2011: 192
PS
*ˁayp-, *pa(y)ˁ- - kid (SED II No. 49)
PS
*ˁVz- - bird of prey (SED II No. 51)
PS
*bVˀ(w)-, *būh- - owl (SED II No. 52)
PS
*bˀr - to catch, to fish, to hunt (EDA I 94)
PS
*biˀr-, *buˀr(-at)- - well, source of water (Fronzaroli 1971: 611, 632, 640; Kogan 2011: 192)

One can easily surmise that the u-forms have secondarily emerged under the influence of b, at least some of them are quite ancient and may reflect a secondary lexicalization of the two variants as early as in PS (perhaps with semantic specification “well” vs. “pit”). Note that for Fronzaroli 1971, 611 *buˀr- is diachronically primary with respect to a more innovative *biˀr-, which is hard to explain in phonological terms.

PS
*bˀš - to be of bad quality, to be putrid, to stink (EDA B N5)
PS
*bVˁbVˁ- - blister, boil (SED I No. 30; Kogan 2011: 230)
PS
*bˁl - to own (Kogan 2011: 237)
