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 beautiful’ (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 beautiful’.
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 beautiful’.
būnu - features, face; plan, shape (of an object), appearance (of the weather) (CAD B 320, AHw. 138)

buppānu - face (SAD I)

A compound noun consisting of būnu ‘face’ and panu ‘face’ (GAG § 59a).
burallu - (a stone) (CAD B 326, AHw 139)
A loanword from Iranian, cf. Parthian bylwr “rock crystal” (Henning 1937, 81), Middle Persian bēlūr ‘crystal’ (Pahlavi 18) and see further Ciancaglini 2008, 128 f. and Beekes 212 where an eventual Indo-Aryan (and, ultimately, Dravidian) etymology is discussed.
