Italicizing Foreign Words and Product Titles

When to use italicization.

When using foreign words in your writing, it is customary to italicize those words as in this example:

To say good night in Spanish, use the phrase buenas noches.

This rule holds true when using a word from any language other than English unless that word has been integrated into the language. For example, the French word critique would not be italicized.

When referring to a product title (e.g. book or movie) it is also customary to italicize the words in the title as in this example:

I love Star Wars movies.
