"Are you on drugs? A proper name represents a UNIQUE thing. Unique things cannot be modiffied by adjectives of quality. It's patently obvious."
"To you and no one else in the known English speaking world."
It's "English-speaking world". Again, you show your ignorance.
"No. You can be skillful at SPEAKING English. You cannot be skillful at English any more than you can be skillful at England."
"Rubbish. English speakers everywhere know what good English is and know you can be good at English just as you can be good at tennis."
Hopeless. You're absolutely hopeless.
"You are a complete moron."
"Since everything you say is wrong, I'm taking this as a compliment. I can't believe you're having fun unless you actually enjoy misinforming people and being castigated for it."
I find people like you an obstacle to be overcome. You know nothing about a topic, and come here and spout drivel, which I must carefully correct.
'Good' or 'bad' refer to common nouns, or words that function as common nouns. The names of wines function as common nouns, provided you use them to mean something generic. Suppose yo buy a bottle of Barolo at the wine shop. 'Barolo' is a regulated name: wine bearing that name must come from a certain area and be made a certain way. It refers to wine made according to the regulations and from a delimited area. But 'Barolo' is not really a single thing, but a brand name. If you buy a bottle of Renato Ratti Barolo Marcenasco 2001, it becomes a proper name. There is no "good Renato Ratti Barolo Marcenasco 2001" or "bad Renato Ratti Barolo Marcenasco 2001", unless you mean a bad BOTTLE of that production run.
The word 'English' functions like "Renato Ratti Barolo Marcenasco 2001", not like 'Barolo'. It is unique, and therefore incapable of being 'good' or 'bad'.
