When I was in high school, I came across the sentence "The Philippines are a beautiful country" in my book of English grammar, the author of which confidently used the sentence as if it were grammatically correct. Take note: The geographical location, the Philippines, the name of which is in plural form, is followed by the plural verb are. Could the grammatical construction be technically justified by the fact that the Philippines is made up of hundreds of islands, making it "many," indeed? Is it not more proper to say, "The Philippine Islands are a beautiful country" or much better, "The Philippines is a beautiful country"?

Philippines is singular just like billiards and economics. I think they're called uncount/non-count nouns. Emotion: smile
