The identification of a. with Lynx chaus is proposed in Landsberger 1934 87 and Salonen 1976 186.
Var. ḫazû, asû.
In AHw. 92 translated as ‘seufzen, jappen’.
Attested once in Malku, equated to Akk. mû “water”.
No definitive etymology can be suggested.
Var.: beʾāru, bêru, baḫāru (baḫāru is attested once in an unpublished letter from Mari).
Var.: bâru. Since Bittner 1911, 147, the Akkadian verb is thought to be related to Mhr. bîter “fischen” (Jahn 1902, 250, not in ML), Jib. ebtér “to hunt” (JL 32), Soq. bˁr “pêcher” (LS 92).
No etymology can be suggested. Cf. perhaps Arb. fwr “to boil; to be agitated, excited” (Lane 2457), even if the irregular correspondence of the labials is hard to explain.
