From Sum. BAR.DA “crosspiece, crossbar” (PSD B 117).
Probably a Hurrian word of an ultimate Indo-European (Mitanni-Aryan) origin.
No etymology can be suggested.
From Sum. BAR.SAL (describing a sheep, PSD B 125).
The origin of Akk. barsillu (the reading barsīlu is also possible) is obscure.
The Akk. word is attested once in a late lexical list (if the restoration is correct) where it corresponds to Sum. (dug)BAR.si-il-la “cracked pot” (cf. PSD B 128, Sallaberger 1996, 98). The exact pronunciation of the Akk. word is uncertain. It appears to be a late “learned” borrowing from Sumerian (III or later).
According to Limet 1976, 24, it could be a loanword from Sum. BAR.SI 'an emmer flour' (PSD B 127).
Or bāru, barru. No etymology can be suggested.
No definitive etymology can be suggested. The Akkadian verb has been usually identified with Hbr. bˀr (pi.) “to explain, to elucidate” (HALOT 106), JPA bˀr (pa.) “to explain, to interpret” (DJPA 83). Of interest is also Arb. bwr “to try, to prove by experiment or experience, to examine” (Lane 274).
Cf. bussumu 'pleasant' (CDA 50).
