Akkadian
birītu, berītu, birittu - fetter, clasp (CAD B 252, AHw. 129)
No etymology can be suggested. Hardly the same as birītu “space between, baulk” in view of the semantic difference.
Akkadian
birku, burku - knee, lap (CAD B 255, AHw. 129)
-­u-­ in Akk. (alongside with ­-i-­) and Arm. (Syr. and Mnd.) is likely a secondary development under the influence of b-­. For the meaning 'lap', see *barak-­ 'chest, thorax'. See discussion in [Holma 1911 95] where the author tends to treat birku 'knee' and birku 'genitals' as the same word, quoting, at the same time, Arb. rakab-­ 'pubis' as a possible cognate to the latter.
