斜体是一种字体，字母向右倾斜：这句话是用斜体印刷的。（如果你是用正楷写东西，那么斜体的意思就是下划线。）除了下面引用的标题和命名惯例外，斜体还用来强调句子中的单词和短语。例如，如果你把最后一个字斜体化，“你打算穿那个吗？”这个问题的意思就完全不同了

快速事实：斜体字

• 来自拉丁语的“意大利”
• 动词：斜体。
• 发音：ih TAL iks

将斜体与样式指南一起使用

虽然在正式的学术写作中适当地使用斜体字很重要，但斜体字在不太正式的交流中并不总是可用的，比如在电子邮件和短信中。新闻、医学写作和各种其他形式的专业写作材料依赖于多种风格指南之一，包括美联社或美联社风格、美国医学协会（AMA）风格和芝加哥风格手册。此外，许多公司、网站和出版公司都有自己的风格指南，必须遵守这些指南进行书面交流。斜体字的使用因样式而异。（例如，在AP样式中，标题放在引号内，而不是斜体。）

综合利用

对于书籍和学术作品，以下一般规则适用，然而，在开始任何写作项目之前，最好检查是否需要遵守特定的风格指南。

将全部作品的标题斜体化：

• 专辑和CD:1989泰勒·斯威夫特
• 书籍：《杀死一只知更鸟》哈珀·李
• 杂志和期刊（印刷版和在线）：体育画报、Slate和语言学杂志
• 报纸：《纽约时报》
• 电影：火星人
• 剧本：洛林·汉斯贝里的《阳光下的葡萄干》
• 软件程序：Microsoft PowerPoint
• 电视节目：Who博士
• 电子游戏：侠盗猎车手V
• 艺术作品：爱德华·霍珀的《夜鹰》

相对较短的作品，如歌曲、诗歌、短篇小说、散文和电视节目片段的标题应加引号。

一般来说，飞机、轮船和火车的名字都用斜体字表示；英语句子中使用的外来词；以及作为单词和字母讨论的单词和字母：

"These are the voyages of the starship Enterprise." —Title sequence from the original Star Trek series "From 1925 to 1953, a passenger train named the Orange Blossom Special brought vacationers to sunny Florida from New York." "There is no danger that Titanic will sink. The boat is unsinkable and nothing but inconvenience will be suffered by the passengers." —Phillip Franklin, Vice President of White Star Line "Come kiss me, and say goodbye like a man. No, not good-bye, au revoir." From "Chats With Jane Clermont" by William Graham "Every word she writes is a lie, including and and the." —Mary McCarthy on Lillian Hellman

作为一般规则，使用斜体强调单词和短语，但不要过度使用此设备：

"Then I started reading this timetable I had in my pocket. Just to stop lying. Once I get started, I can go on for hours if I feel like it. No kidding. Hours." —From The Catcher in the Rye by J. D. Salinger,

观察

"Italics rarely fail to insult the reader's intelligence. More often than not they tell us to emphasize a word or phrase that we would emphasize automatically in any natural reading of the sentence." —From "The Philosophy of Punctuation." Opera, Sex, and Other Vital Matters by Paul Robinson, University of Chicago Press "Think of italics as butterflies that might swoop across the page, allow them to flit about, land here and there, softly; gently; don't treat them as a blanket that must spread itself across the entire page. The butterfly approach will bring a dash of color; the blanket approach will darken everything." —From Noble's Book of Writing Blunders (and How to Avoid Them) by William Noble, Writer's Digest Books "Underlining is to... handwritten papers what italics are to more formal publishing... Today the only widespread use of underlined text is to denote clickable links in Web documents. (The newspaper convention, which I use as a newspaperman and which was also a response to a technical inability to use italics, is quotation marks for book, movie, and other titles.)" —From The Elephants of Style by Bill Walsh, McGraw Hill
