mn - what; the one who, who, who(so)ever
(DUL 560)
It is possible that the pronoun should be differently vocalized in the meaning “what”, on the one hand, and “who”, on the other hand (see PS *mann- ‘who?’ and *mīn- ‘what?’). The forms with n are used as synonyms for my and mh. See Kogan 2009:72.
Very uncertain (Pardee 1985:50), comparison with Akk. mundu ‘groats’ (CAD M₂ 201) assumed as certain in Watson 2007:69 remains difficult in view of the final -γ (Kogan 2015:365).
