Which statement correctly describes abbreviation use on first use and thereafter?

• A. Use "U.S." on first use; then "the U.S." or "U.S." thereafter; remain consistent.
• B. Use "U.S." on first use only; never again.
• C. Use "U.S." on first use; then "the U.S." or "U.S." thereafter; remain consistent.
• D. Use "the U.S." on first use; then "U.S." thereafter; remain consistent.

Answer: (C)

Introducing abbreviations at first mention helps readers connect the shorthand with the full term. For the United States, using "U.S." on the first use establishes the abbreviation clearly. After that, you can refer to the country with either form—"the U.S." or "U.S."—but you must stay with the same form for the rest of the piece. This keeps the writing concise while maintaining clarity, and it avoids confusing readers with mixed references. The choice between "the U.S." and "U.S." after the first mention often reflects how you’re treating the term (as the country as a political entity or as a modifier), but the essential practice is consistency throughout the text.
