Akkadian
būṣu - hyena (CAD B 349, AHw. 143)

derived from PS *ṣ̂VbVˁ with metathesis

Akkadian
buṭnu, buṭumtu - terebinth (AHw. 144, CAD B 358–59)
Akkadian
buˀû - to look for, to search for (CAD B 360, AHw. 145)

Mostly in Babylonian and, remarkably, never in Old Assyrian, where šeˀāˀum is normally used instead (Kogan 2006c:195). CAD B 365 is right to point out that the meaning “to wish” for buˀˀû, widely attested in some peripheral varieties of Akkadian, is likely due to WS influence.

Akkadian
daˀāmu - to be(come) dark, dim (AHw. 146)
Akkadian
dabû - bear (CAD D 17, AHw. 148)

Attested in a few SB literary texts and lexical lists, in earlier periods in proper names only. Cf. further Landsberger 1934: 82-3, Salonen 1976: 194-5. Geminated -b- i n da-ab-bu (Malku V 50) is probably due to a WS influence.

Akkadian
dadānu (diadānu, daddānu) - neck muscles (CAD D 17; AHw. 148)
Akkadian
daddaru - an ill-smelling, thorny plant (CAD D 17, AHw 148)
Akkadian
dādu - paternal uncle (Kogan 2014: 91–92)

Durand 1983 : 216–217; Wilcke 1985 : 220; Durand 1992 : 120–121, 2001–2002 : 752–753
The term belongs to the "Amorite" system of kin designations and is attested mainly in Mari corpus; Akkadian proper employs analytical expressions to designate uncle and aunt, e.g. aḫi abim, aḫāt abim and so on.

Akkadian
dādu - love-making; object of love, darling, favorite (CAD D 20, AHw. 149)
Akkadian
dalû - to draw water from a well (CAD D 56; AHw. 155)
