|The punctuation marks are not used grammatically, but to indicate
intonation. The period indicates a falling, or final, intonation contour,
not necessarily the end of a sentence. Similarly, a question mark indicates
rising intonation, not necessarily a question, and a comma indicates "continuing"
intonation, not necessarily a clause boundary. In some transcript fragments
in your readings you may see a combined question mark and comma, which indicates
a rise stronger than a comma but weaker than a question mark. Because this
symbol cannot be produced by the computer, the inverted question mark is used for this purpose.
