Finding every word in a passage that shares a specific prefix or suffix — words starting with "un", or ending in "-ing" — is useful for language learning exercises, word game strategy, or linguistic analysis of a text's vocabulary patterns.
This tool scans your pasted text for every word matching your chosen prefix or suffix, case-insensitively, and lists each match along with a running total count.
This is useful for teachers building vocabulary exercises around a specific word pattern, word game players hunting for valid word options, or writers checking how often a particular prefix or suffix pattern recurs throughout their own text.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.
The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.
Frequently asked questions
Is the matching case-sensitive?
No, matching is case-insensitive, so searching for the prefix "un" catches both "unusual" and "Unusual" equally.
Are duplicate word matches listed more than once?
Yes, every occurrence in the text is listed, since the tool is scanning for pattern matches throughout the passage rather than compiling a unique word list.
