Java Regex – Match Word with All Misspellings

In this tutorial, I am giving a short example of matching all common misspellings along with any word in a text content. An example could be of word “calendar”. Common misspellings of calendar will possibly include incorrect use of vowels at position 2, 4, and 7. In this example, I will check for wrong characters at these positions only. You can modify the example code as per your need.

Regex to match ‘calendar’ with misspellings


Above regex will be able to match the word calendar as well as all of it’s common misspellings.

Example Usage of Regex

package examples.regex;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class MatchMisspellingsExample
   public static void main(String[] args)
      String content = "This is may calandar. This is june calander. This is may calendar.";
      String regex = "c[ae]l[ae]nd[ae]r";
      Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);
      Matcher matcher = pattern.matcher(content);
      while (matcher.find())
         System.out.print("Start index: " + matcher.start());
         System.out.print(" End index: " + matcher.end() + " ");


Start index: 12 End index: 20 calandar
Start index: 35 End index: 43 calander
Start index: 57 End index: 65 calendar

I will suggest to modify above example code and play with it for more possible misspellings you can think of, and then try matching them.

Happy Learning !!
