Some of the most misused and misunderstood pieces of punctuation are also the smallest. This program provides a practical review of two important punctuation marks - apostrophes and speech marks. We begin with the troublesome apostrophe, its origins, functions and the reasons why it remains a necessary part of the English language. The program provides a detailed look at how to use apostrophes to indicate possession and to spell contractions. We also revise the proper use of quotation (or speech) marks, and examine some common errors in using these tricky punctuation marks in written expression.
