Hi,

I have many questions about some abbreviations.

Is it right to write USA  with full stops U.S.A ?

Is it correct to write the abbreviations for Noun , verb , adjective and adverb with capital letters ? and Is it correct to right the abbreviations for directions with small letters instead of capital ones ?

Thanks a lot in advance,

Noor

1.      If you research this first question, you will see that there are several acceptable forms of abbreviating the name of the country, especially since the U.S. post office started preferring abbreviations with no periods.  Most sources simply recommend that you be consistent in your abbreviations. The following rule comes from the University of Colorado style sheet:

Use periods with the two-letter abbreviation for United States. Do not use periods with the three-letter abbreviation for United States of America. Use the abbreviation U.S. only as an adjective. Spell out United States when it is a noun.

• The U.S. government is one of the nation�s largest employers.
• Most of their products were made in the USA.
• CU-Boulder is recognized as one of the premier public universities in the United States.

2.      Parts of speech are not written with capital letters.

3.      The following rule from Purdue OWL is standard for the capitalization of directions:

Capitalize directions that are names (North, South, East, and West) when used as sections of the country, but not as compass directions. 

�         The Patels have moved to the Southwest.

�         Jim �s house is two miles north of Otterbein.
