Wait - how did cuptor become cuproarele? Thanks
"Un cuptor" is masculine; "cuptoarele" is feminine. I think this because "cuptor" is a neutral noun, having masculine tense in the singular and feminine tense in the plural. Can someone who knows Romanian please confirm if this is correct?
Yeah, kind of exactly. Of course, the plural ending -uri is really rare among feminine nouns, but excluding this, plural neuter nouns behave like plural feminine nouns.
