Frequently Asked Questions

How do I use the underscore wildcard for pattern matching?

Use underscore (_) to represent any single letter. For example, '_at' finds words like cat, bat, hat, mat. Use 'th_' to find the, this, that. You can use multiple underscores: '__at' finds words like coat, boat, goat (4 letters ending in 'at').

Can I find words of a specific length without knowing the letters?

Yes! Change the pattern type to 'Word length' and enter a number. For example, enter '5' to find all 5-letter words, or '3' for all 3-letter words. This is perfect for word games, crosswords, and creating educational exercises.

What's the difference between case-sensitive and case-insensitive matching?

Case-insensitive (default) treats 'Cat' and 'cat' as the same word. Case-sensitive treats them as different. Use case-sensitive when analyzing proper nouns, acronyms, or when exact capitalization matters for your educational or research purposes.

How can I find words that start or end with specific letters?

Use the pattern type dropdown. Select 'Starts with' and enter letters like 'pre' to find words beginning with 'pre'. Select 'Ends with' and enter 'ing' to find words ending in 'ing'. No wildcards needed - just type the exact letters you want to match.

Can I save or export the highlighted text and word lists?

Yes! Use the copy button to copy the results to your clipboard, or the download button to save as a text file. The exported text preserves the original formatting with clear indicators showing which words matched your pattern, perfect for educational materials and research documentation.
