*ˁwn - to help, to aid (Renfroe 1992:22‒24; Kogan 2015: 323)

Akkadian
taḫanātu - help, favour (AHw 1301, CAD T 40)

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.

 

Hebrew
māˁōn - refuge; habitation (BDB 732)

The distinction between ˁōn I ‘help, assistance’ and ˁōn II ‘dwelling’ introduced in HALOT 610, where the two terms are traced to different WS roots, does not seem well-founded
