Akkadian

ḫiṣnu - protection (CAD Ḫ 203, AHw. 348)

SB lexeme. Unlikely to be autochthonous in view of the irregular ḫ coupled with the late attestation. Rather, we must be faced with WS loanword, even if the exact source of borrowing is not easy to establish (not Aramaism because of ṣ).

PWS
*ḥVṣ̂n- - lap, bosom (SED I No. 129; Kogan 2011: 218)
