Here's how to use these helpful punctuation marks:
When you write, use quotation marks to enclose a cited speaker's or writer's exact words; use them to set off the titles of short works, such as stories, magazine articles, poems and songs, as well as words and phrases used in a special or unusual way (irony and jargon).
British printing generally uses single quotation marks for speech, but double quotation marks for a quotation within a quotation. For example: John said, 'I wonder who wrote "To be great is to be misunderstood."? Rachel thinks it was Emerson.' If the first and second quotations end together, put a double quotation mark, then a single quotation mark after the final punctuation: John said, 'I wonder who wrote "To be great is to be misunderstood."?' Do just the reverse at the start of the quotation - single followed by double quotation marks- if the first and second quotations begin together.
If the punctuation is part of the quoted matter, it goes inside the quotation marks.
If a quotation has more than one paragraph, begin each paragraph with quotation marks but use them to close only the final one.
