How Do I Spell Check with PDF readers?

A lot of software comes with different ways to spell-check; below is a list of PDF readers with spell checkers and how to use them.

Microsoft word

The Microsoft Word software makes spell checks easy. If you did not write your PDF with Microsoft Word, you could still edit with Microsoft Word. These are the steps to spell check on Microsoft Word.

  • Open the file using Microsoft Word.
  • Spelling mistakes will be highlighted with a red underline, while grammar mistakes will have a blue underline.
  • Right-click on the underlined words, and it will bring suggestions for the correct spelling. Click on the right word.
  • There are some simple words the app autocorrects without underlining or suggesting. If you keep correcting a spelling, you can right-click on it and add it to autocorrect.
  • If there are new words that you keep using and it is being underlined, right-click and add to the dictionary. When you add a word to the dictionary, it will no longer be seen as a wrong spelling.

If you do not want to keep scrolling to check for the underlined words, Microsoft Word can bring the suggestions to a side of the writing.

  • Click on the review tab in the options above.
  • Then click on 'Spelling and Grammar.'
  • The suggestions will show by the side of the article. Click on the words and choose the right word.
  • If a word is misspelled more than once, click on 'Change all,' and it will correct all the misspelled words.
  • If you intentionally misspell a word, click on 'Ignore once' to remove the suggestion.

PDF element

After you have saved the PDF, open with PDF element software and follow these steps.

  • Go to the File menu, and click on preferences.
  • Enable the spell checker and select PDF element as your custom dictionary

Tips to Accurate Spell Checking

While using some spell checkers, the message you were trying to convey has been changed. To avoid minor mistakes in your PDF, these are other tips for checking your spelling and grammar.

  • Use more than one spell checker

If you type with software with the spell checker activated, you can cross-check with another software. If you missed an error in the first software, the second software should point it out and make corrections.

  • Take some time off

If you have been on the computer for too long, you tend to miss the minor mistakes. Take some time off to do other things and come back to it. When you get back, you might notice some errors you missed.

  • Read Aloud

Even though reading aloud sounds strenuous, it is very effective in noticing mistakes. Reading it aloud will enable you to detect errors faster because you tend to read more slowly when you read aloud. However, this might not be feasible if the PDF is a long one.

  • Read Headlines

Headlines are easy to overlook when we check for mistakes. Ensure you do not miss any spelling or grammar mistakes in the headlines.

  • Ask a friend

Much more effective than checking with software and reading it yourself. You could ask a third party to help you crosscheck the writing. A third party reading from scratch has no idea what it is about, so they will read with an open mind and quickly notice mistakes.

  • Print it Out

If the work is short, you can print it out. After staring at a screen for too long, looking at a hard copy of writing will make you easily spot mistakes. Even though you will not be able to correct the hard copy, you will be able to point out spelling mistakes you did not notice.

As little as spelling mistakes can be, they can make your work or presentation look unprofessional.

Make efforts to double-check and ensure your work is error-free. Use apps that support spell checks and crosscheck with external software.
