Words

Akkadian
bulû, bulāˀu, bulīˀu - firewood (CAD B 312, AHw. 137)
At first sight, von Soden’s derivation from balû “to become extinguished” appears scarcely compatible with the meaning “firewood” postulated for this lexeme. Still, in view of the meaning “to be old (of things)” of PS *b-l-y, from which the Akkadian verb is thought to be derived, it is noteworthy that in bulû corresponds to Sum. {giš.sumun} “old wood”, further equated with Akk. iṣṣu labiru id
Akkadian
bunbullu - (mng. uncert.) (CAD B 317, AHw. 138)
Or punpullu. No etymology can be suggested.
Akkadian
bunnannû - general region of the face (especially the eyes and nose); outer appearance, figure, likeness, features (CAD B 317, AHw. 138)
Var. bunnānû.
Most probably, from banû ‘to build’ (AHw), even if the derivational pattern is unclear (Kraus 1935, 46, GAG § 57b Anm.). This etymology is particularly appealing in view of the fact that Punnānū can also mean ‘creature’ (Lambert 1998, 153). A derivation from banû ‘to be beautifuľ (CAD) seems to be based on the assumption that Punnānū is related to būnu ‘face’ which, in turn, is commonly derived from banû ‘to be beautifuľ.
Akkadian
bunnunu - to please (?) (CAD B 319, AHw. 138)
One should perhaps agree with von Soden (AHw. 138) that bunnunu is an (erroneous?) variant of the D-stem of banû ‘to be beautifuľ.
Akkadian
būnu - features, face; plan, shape (of an object), appearance (of the weather) (CAD B 320, AHw. 138)
Var. bunnu.
Usually derived from banû ‘to be beautifuľ (AHw, CAD).
Akkadian
būnu - a bird (CDA 48)
Or bunu. No etymology can be suggested.
Akkadian
bunzirru - web, blind (CAD B 322, AHw. 138)

Akkadian
buppānu - face (SAD I)
Cf. buppāniš ‘face down’ (CAD B 332, AHw. 139, CDA 48); buppānam ‘face down, flat on the face’ (CDA 48).
A compound noun consisting of būnu ‘face’ and panu ‘face’ (GAG § 59a).
Akkadian
burallu - (a stone) (CAD B 326, AHw 139)
A loanword from Iranian, cf. Parthian bylwr “rock crystal” (Henning 1937, 81), Middle Persian bēlūr ‘crystaľ (Pahlavi 18) and see further Ciancaglini 2008, 128 f. and Beekes 212 where an eventual Indo-Aryan (and, ultimately, Dravidian) etymology is discussed.
