{nay’ DIlmeH Huch} is not a noun-noun construction. It’s not a “genitive” (termed “possessive” in TKD). It is money for-the-purpose-of-buying-a-dish-of-food. It’s money with a mission.

Note that this is an uncommon construction, probably not justified by canon, because the general rule is that while a verb with {-meH} can describe the purpose of a noun or it can describe the purpose of a verb, there is a distinctive difference in form depending on whether it describes a noun or a verb.

When it describes a noun, the verb with {-meH} will, in all examples I’ve seen, NOT HAVE A SUBJECT OR OBJECT.

Untrue.
