Probably an early WS loanword reconstructible as *ta-ˁān-at- ‘help, support’. This rather plausible etymology is not free of difficulties: 1) Early WS loanwords are rather uncommon in texts from the core Babylonian area. 2) The root ˁwn is not so common in the NWS languages. 3) The morphological shape *ta-ˁān-at- is not the expected one in the present case. See EDA II for details.
