How to Add a Free Thesaurus to Look Up on Your iPhone & iPad

* This post is part of iPhone Life's Tip of the Day newsletter. . *

I love using a thesaurus when I write, so the absence of this option from the iPhone's dictionary feature, Look Up, used to be a sore spot for me. Beginning with iOS 12, I no longer need a third-party thesaurus app, because a thesaurus is included in Look Up on iPhone and iPad for free! Let's get started learning how to add a thesaurus to Look Up, so you can find just the word you're looking for, be it a synonym or antonym.
