¡°Always put the comma inside quotation marks,¡± the professor said.

Then she added, ¡° The same goes for the period.¡±

¡°Does the same rule apply for the question mark?¡± he asked.

¡°Only if the entire statement is a question,¡± she replied, ¡°and never add a comma after a question mark. Also, be sure to lowercase the first word of a continuing quote that follows an attribution and a comma.

¡°However, you must capitalize the first word of a new sentence after an attribution,¡± she continued. ¡°Do not forget to open and close the sentence with quotation marks.¡±

¡°Why are there no quotation marks after the word ¡®comma¡¯ at the end of the fourth paragraph?¡± he asked.

¡°Because the same person is speaking at the beginning of the next paragraph,¡± she said. ¡°Notice that the new paragraph does open with quotation marks. Note, too, that a quote inside of a quotation needs a single quotation mark, as around the word ¡®comma¡¯ above.¡±
