The first piece of presidential oratory opened with several sentences marked by asyndeton, the omission of conjunctions for dramatic effect.  The speech jars the reader with a barrage of uncoordinated ideas and images.
 

Good evening. Today, our fellow citizens, our way of life, our very freedom came under attack in a series of deliberate and deadly terrorist acts. The victims were in airplanes, or in their offices; secretaries, businessmen and women, military and federal workers; moms and dads, friends and neighbors. Thousands of lives were suddenly ended by evil, despicable acts of terror. (George W. Bush 9-11-01)

Later speeches would use polysyndeton or the conscious use of conjunctions to elongate sentence rhythms and create a stately rhetoric appropriate to national mourning.


 Grief and tragedy and hatred are only for a time.  Goodness, remembrance, and love have no end. And the Lord of life holds all who die, and all who mourn. (George W. Bush 9-20-01)
