How to Add a Word to the Dictionary in MS Word: A Step-by-Step Guide

Adding a word to the Microsoft Word dictionary is a straightforward process. All you need to do is right-click the word that has been flagged as incorrect, and then click on “Add to Dictionary.” This will ensure the word is recognized in future documents, and you won’t be interrupted with the red squiggly line again.

After you add a word to the dictionary, Microsoft Word will recognize it as correctly spelled in all your documents. This can be particularly useful for names, technical terms, or newly coined words that are not yet in the standard dictionary.


Have you ever been typing away on Microsoft Word, only to be constantly pestered by that pesky red squiggly line under words you know are spelled correctly? It’s like a persistent mosquito buzzing around, insisting that your name, a technical term, or the latest internet slang is a mistake. This interruption can break your flow and slow down your writing process. But here’s the thing: you can take control and teach Microsoft Word new words. In fact, adding words to the Microsoft Word dictionary is an essential skill for writers, students, professionals, and anyone who uses specialized vocabulary.

Whether you’re working on a novel with unique character names, drafting a scientific paper with complex jargon, or just trying to get Word to recognize your favorite colloquialisms, knowing how to expand your dictionary is going to save you time and frustration. So, let’s dive into the specifics and get your dictionary customized to your writing needs.

Step by Step Tutorial on How to Add a Word to the Dictionary in Microsoft Word

Before we begin, make sure your Microsoft Word application is open and you have a document ready.

Step 1: Right-click the word

Right-click on the word that has been underlined with a red squiggly line.
This tells the software that you want to make changes to this specific word.

Step 2: Select “Add to Dictionary”

From the right-click menu, select the “Add to Dictionary” option.
This will instantly add the word to your custom dictionary. Microsoft Word will no longer mark this word as misspelled in any document.


Personalized DictionaryHaving a dictionary tailored to your specific needs can improve your writing efficiency.
Time-SavingNo longer will you need to regularly ignore the same “errors,” saving you valuable time.
FlexibilityYou can add any word you like, allowing for creative language use and technical language accuracy.

Adding words to your Microsoft Word dictionary means you can create a document that reflects your unique voice or professional terminology without being second-guessed by spellcheck.


Potential OveruseUsers might add words accidentally or too liberally, reducing the effectiveness of spellcheck.
Not TransferableCustom dictionaries are local to your machine and won’t carry over to other devices unless you export them.
Limits LearningRelying too heavily on custom dictionaries may limit your exposure to correct spelling and grammar norms.

Customizing your dictionary should enhance your writing, not detract from the fundamentals of good spelling and grammar.

Additional Information

When it comes to expanding your dictionary in Microsoft Word, there are a few additional nuggets of knowledge worth mentioning. For instance, did you know that your custom dictionary isn’t limited to just one language? That’s right, you can add words from different languages, and as long as you have the relevant editing language installed, Word will recognize them.

Plus, if you’re using Microsoft Word across multiple devices, there’s a way to ensure your dictionary follows you around. You can export your custom dictionary and import it into Word on another device. Handy, right?

Also, for those who are serious about their writing, consider creating multiple custom dictionaries. This allows you to switch between projects with different lexicons easily. For example, one dictionary for technical terms, another for a fantasy novel, and so on. Remember, the goal of adding words to the dictionary in Microsoft Word is to make your writing process smoother and more efficient.


  1. Right-click the word
