Italics
Italic type serves to make text stand out distinctively. It may be
employed for stylistic reasons, lending emphasis, irony or urgency
to what it encompasses, or for reasons of convention.
Its main uses are the following:
• Highlighting words that have special significance
• Emphasizing a speaker's words
• Setting off non-English words
• Setting off terms, titles and other special text
• Underscoring a point in a quote
