Look Up: Check Any Word In The Dictionary | iOS 17 Guide

Quickly find the definition of any word using the built-in dictionary. While using any apps that allow you to select text, tap and hold a word, then tap the Look Up option.

As well as the definition, you also get example uses, phrases that use the word, its origin, and even famous people with that word as their surname.

More than a dictionary

Pressing Look Up can also show personalized suggestions from other apps, as well as nearby locations, film showings and more. Where relevant, you’ll see some of the same features from the Spotlight view in addition to dictionary definitions.
