Commas in Addresses and Dates
Technically, we could explain the later parts of an address as reduced subordinate clauses -- "San Francisco, *which is in* California." Similarly, with dates, we could explain the year as an ellipsed prepositional phrase -- "July 16, *in (or) of* 1934.) Such technicality, however, is probably not worth the trouble in discussing every sentence. 1. Rio de Janeiro, Brazil, has one (DO) {of the most beautiful harbors} {in the world} [#1]. | 2. Abraham Lincoln was shot (P) {in Washington, D. C.}, {by John Wilkes Booth} {on April 14, 1865}. | 3. New Orleans, Louisiana, has many sugar refineries (DO). | 4. George Washington was inaugurated (P) {on April 30, 1789}. | 5. Thomas Edison lived {in Menlo, Park New Jersey}. | 6. Boston, Massachusetts, manufactures many shoes (DO). | 7. The naval stores will be shipped (P) {from Savannah, Georgia}, {on April 26, 2010}. | 8. Many railroads pass {through Birmingham, Alabama}. | 9. The Clermont made its first successful trip (DO) {on August 17, 1807}. | 10. We visited Santa Barbara, California, (DO) {in December, 1986}. | Note |
