Hello all. Thank you for your help last time. I came back with another mind-boggling question (well, at least it is that confusing to me), and hope some of you will be able to cast light on this issue once and for all.
I know that country names such as the United States of America or the Republic of Korea must have a definite article. But, how about when they are used as an adjective?
1. For example, is it OK to say “prohibited by a US regulation” or “an US automobile company”?
2. Does the grammar rule applied to #1 change if those abbreviations are spelled out? (e.g. an United States automobile company)
3. The answers to #1 and #2, are they same for other countries such as the ROK, the Philippines, and so on? Thank you for your time and consideration
