Example: *Canis lupus* is the scientific name for the gray wolf.
5. Legal Terms: Some legal terms, such as *habeas corpus*, are often italicized.
6. Technical Terms: Italics can be used to highlight technical terms that are specific to a particular field.

Example: *Dictionary definition*: "A word or phrase that is italicized is one that is emphasized."
8. Clarity: In some cases, italics can be used to make text clearer or easier to read. For example, if you have a quote within a quote, you might use italics to indicate the inner quote.
