Translation:I want eight buttons and four green handkerchiefs.
"I want eight green buttons and four handkerchiefs." was considered wrong. I suppose that the adjective could (not necesairly) modify both nouns in Romanian. Is there a way to modify both numbered nouns in English with just one adjective, like I tried in my answer, or would I need to specify "eight green buttons and four green handkerchiefs"? Sorry for bothering y'all with a doubt that is not even about the target language. Cheers.
