''The Canadian Oxford Dictionary'', second edition. Toronto, Oxford University Press. {{ISBN|0-19-541816-6}}.</ref> and '''speech marks''') are [[punctuation]] marks used in pairs to mark a section of text as speech, a [[quotation]], a phrase, or an unusual word. They are used in groups of 2, as a pair of opening and closing marks. They are used in either of two forms: {{nowrap|single (‘…’)}} or {{nowrap|double (“…”)}}. Depending on the [[font|typeface]], the opening and closing quotation marks may be identical in form (called “vertical” or “straight” or “typewriter” quotation marks), or they may be distinctly left-handed and right-handed (“typographic” or, colloquially, “curly” quotation marks). The closing single quotation mark is identical or similar in form to the [[apostrophe]], and similar to the [[Prime (symbol)|prime]] symbol. However, these three characters have quite different purposes.

Double quotation marks are used as a rule in the United States, while both single and double quotation marks are used in the [[United Kingdom]] and other [[Commonwealth of Nations|Commonwealth countries]] (except [[Australia]] and [[Canada]]).

However, the style of opening and closing quotation marks must be matched: : ‘Good morning, Frank,’ said HAL. : “Good morning, Frank,” said HAL. For speech within speech, the other mark is used for inner quotations, within a quotation: : Frank reported
