When it comes to using italics, there are a few key situations where they're absolutely necessary. For example, when you're quoting a title of a book, movie, or album, it's common to use italics to set it apart from the rest of the text. Think of it like putting a frame around a beautiful painting - it helps it stand out and look more appealing.
In addition to titles, italics are also used to indicate foreign words or phrases that are being used in a sentence. It's like adding a fun flavor to your writing, giving it a bit of international flair. And, let's be real, who doesn't love learning new words and phrases from other languages?
