A derivation from Sum. PANA “bow” has been proposed (see SAD I 62). This etymology is mainly based on the comparison of bīt pa-ne₂-e with Akk. bīt ḳašti “bow-case” (CAD Q 155, lit. “home of the bow”). However, the context provides no strong evidence for the meaning “bow-case” of bīt pa-ne₂-e, and in view of the late attestation of the word in question its interpretation as a Sumerism is rather unlikely.
