Part II in our never-ending battle with "the": proper nouns and articles

1) proper noun
Proper nouns (고유명사) are nouns that represent unique entities, such as names, places, and things. Generally, you need to capitalize the first letters, and should not put "the" before them.

• Seoul, Tokyo, Samsung, Hong Gil-dong .... (o)
• seoul, tokyo, the Samsung, hong gil-dong .... (x)

But common nouns (일반명사) also serve as proper nouns when paired with other words to create a name for an entity. For example, words like ministry, trade, and foreign affairs are all common nouns, but the Ministry of Foreign Affairs and Trade is a proper noun. This kind of proper nouns are generally preceded by the.

• the Department of State, the Harvard School of Government, the White House ... (o)
  
• Department of State, Harvard school of government, the white house ... (x)
  

2) proper noun + description
You need to determine which article to use depending on whether the proper noun is preceded or followed by the description thereof. Take a look at the following examples:

• The American tire maker Goodyear did...
• Goodyear, an American tire maker, did...
• American tire maker Goodyear's action is.... (You are pairing "American tire maker" and "Goodyear" into one proper noun. So no "the". It is like you never say "the Tom's book." You should always say "Tom's book")

• The Korean car company KIA said...
• KIA, a Korean car company, said...
• Korean car company KIA's sales increased...
  

3) Acronyms
I have already tried to explain this in another post (April 3, 2010 "Frustrated with a/an/the? You are not alone!"), but a lot of people still seem to be very confused. Let me give it another try!

When common nouns are paired to form a proper noun, the end result is generally a very long proper noun. So people usually use acronyms. For example, instead of saying "the Ministry of Foreign Affairs and Trade," people say MOFAT. A lot of Korean students are not sure about which article (a,an, the) to put before acronyms.

• The FBI, the CIA, the UN ... : For acronyms of organization names that you pronounce each letter separately, use "the."
• WIPO, UNICEF, UNESCO, NATO ... : For acronyms of organization names that are pronounced as one word, do not put "the" before them.
• BP, LG, KFC, AT&T ... : Even if you pronounce each letter in these acronyms, they are so commonly used that they became non-acronymous proper nouns. That is, no one really cares what each letters stand for any more. In this case, do not use "the."
