Fastest Ways to Look Up Word Definitions on Mac

Look Up Definitions Mac Featured

Apple’s built-in dictionary is one of those software pieces that everyone uses but never talks about. It’s an invaluable resource that doesn’t get nearly enough of the attention it deserves. The pop-up dictionary has been around for some time, yet millions of Mac users might be unaware it exists. How can you make the most of Apple’s dictionary functions? Let’s take a look at the fastest ways you can look up word definitions on Mac.

Built-in Shortcut

One of the fastest ways to look up a word definition on a Mac is built right into the software. It’s as easy pressing Command + Control + D on your keyboard. Whatever word is currently beneath the mouse cursor will have a pop-up appear with the definition(s).

There are some caveats to this process, as it doesn’t work everywhere. On most browsers, it should work across the Web, but sites like Google Docs are seemingly excluded from the function.

Alongside the keyboard shortcut, Apple also offers another quick way to quickly look up word definitions in apps or when browsing the Web.

1. When you are in an app or on a website, press the Control button on your keyboard and click on your left mouse button.

2. A shortcut menu will appear above the word. Select the first option: “Look Up.”

Inside the Look Up window, you have a number of options available:

1. Choose to see the full definition of a word. Just click “more” at the end of the shortened definition.

3. If you want to see more information, select a category at the bottom of the pop-up. Alternatively, swipe left or right on the trackpad and move between various categories.

Set Your Own Keyboard Shortcut

While Apple’s existing keyboard shortcut suffices for short definitions, maybe you want something with a little more detail. In that case, you will need to establish your own keyboard shortcut for the Dictionary app.

1. Go to the Apple menu at the top-left side of the screen and open the “System Preferences” menu.

2. Click the keyboard option.

5. On the right side of the preferences, scroll until you find “Look Up in Dictionary.” To the right of that, it should say “none,” as no keyboard shortcut previously existed.

6. You need to assign your preferred keyboard shortcut at this point. You can choose anything you like. For sample purposes, we’re choosing Command + Shift + Z.

7. Test the shortcut by opening any site or a Google search and clicking on any word. Activate your keyboard shortcut command, and it should open the Dictionary app.
