Sometimes, while browsing the internet, you will come across words you do not understand or subjects you want to learn more about.

The Look Up feature allows you to easily look up the definition of words. Its menu provides links to several options: Apple’s dictionary, other dictionaries, Siri-suggested websites, Wikipedia, the App Store, and more.

You can even use Look Up as a free thesaurus app, or use the Look Up feature in Safari to find additional references to a word or phrase on the internet.

Let’s explore looking up words on iPhone with the Look Up feature.

  • Quickly check the definition of words or phrases with just a few taps.
  • Easily find websites or apps related to specific words.

This tip works on iPhones running iOS 16 or later.
