"Acestea sunt inelele mamelor."
Translation:These are the rings of the mothers.
In the version "These are the mothers rings".... there should be an apostrophe in English. "These are the mothers' rings."
Do the rings have to be articulated? Or, more broadly, when a noun has a genitive/dative noun responding to it, does it have to be articulated?
I learned that with the (possessive) genitive, yes, the noun must have the "definite" article. Think of it as a reinforcement that they are not just any rings, or rings in general, but specifically those that belong to the mothers.
