When incorporating a direct quotation into your writing, the decision to italicize quotes depends entirely on the context and the specific style guide you are following. In most standard prose, the quotation marks themselves serve as the primary indicator that the text is borrowed, and the words inside the quotes retain their original form, including any italics that were present in the source material.
Understanding the Standard Convention
The baseline rule for American English, as outlined in the Chicago Manual of Style and the Associated Press Stylebook, is to avoid italicizing the actual quoted text. Instead, double quotation marks are used to set the speech or writing apart from your own narrative. If the source material you are quoting already contains italics for emphasis or to denote a title, you are required to switch those italics to plain text and insert the Latin word sic in brackets immediately after the error or unusual formatting to indicate that the deviation is from the original, not a mistake in your writing.
Punctuation and Quotation Marks
It is crucial to distinguish between the act of italicizing the quote itself and the placement of punctuation relative to the quotation marks. In American English, commas and periods almost always go inside the closing quotation mark, regardless of whether they are part of the original quote. Question marks and exclamation points, however, are placed inside the quotation marks only if they are part of the quoted material; if they belong to the larger sentence, they appear outside the marks. This structural punctuation rule exists independently of any consideration to italicize quotes.
Exceptions in Academic and Technical Writing
While standard journalism and general prose avoid the practice, there are specific scenarios in academic or technical writing where you might consider it necessary to italicize quotes. When quoting a term that is being discussed as a linguistic example or a defined concept—such as the word lexicon or the phrase "cognitive load"—italics may be used in your prose to visually distinguish the term-in-question from the surrounding text. However, this applies to the word as a linguistic subject rather than the act of quoting it verbatim in a narrative sense.
Handling Titles and Works
Confusion often arises when the object of the quote is a title of a work. Here, the rules shift significantly. You should not italicize the quote, but you must italicize the title of a book, album, or movie that you are mentioning in your sentence. Conversely, if you are quoting a poem or an article, those titles should be placed in quotation marks. The key is to italicize the container and use quotes for the contained item, ensuring your citation remains clear and professional.
British English and Style Variations
If you are adhering to British English conventions, the approach to quotation marks differs slightly, though the principle of italicizing the quote generally does not apply. Single quotation marks are preferred for the primary quote, with double quotation marks used for quotes within quotes. The logic regarding punctuation placement follows similar logic to American rules, with terminal punctuation usually staying within the quoted material. The visual presentation of the text relies on the quotation marks, not on sloping the letters.
When in Doubt: Consistency is Key
Ultimately, the most important factor in handling quoted material is consistency. Whether you are using a manual typewriter or a modern word processor, you should establish a rule and apply it uniformly throughout your document. If you are submitting work to a publication or institution, always defer to their specific style guide. The goal of clear communication is not to draw attention to the formatting of the quote, but to ensure the reader understands the source and context of the language you have presented.
