About The Word Index
The Word Index helps you find the word you almost know. Start with a few remembered letters, a pattern, a rough length, or an idea of how the word sounds, then combine those clues into a useful shortlist.
What It Helps You Do
The front door is a familiar human problem: you know something about a word, but not enough to name it. The tools help you move from that partial memory to a ranked set of possibilities, understand why each one matched, and inspect the underlying evidence when you need it.
Start with:
- Finder – Combine known letters, position, length, sound, and other clues in one search
- Word Explorer – Inspect available senses, forms, pronunciations, relationships, and provenance
- Pattern Finder – Find spellings that match the letter positions you remember
- Anagram Solver – Find compiled-lexicon matches formed by rearranging a set of letters
- Sound and Rhyme Explorer – Search by pronunciation, similar sounds, and rhyme
- Meaning Search – Use sound and remembered-letter clues now; meaning ranking remains in preparation while definition evidence is reviewed
Portfolio Boundaries
The Word Index does not duplicate game-specific products. Five-letter deduction, accepted guesses, answer history, and opener analysis belong at FiveLetterWords. Clue-aware solving, crossword answers, construction, and crossword-specific vocabulary belong at Solve The Crossword. Links between the products appear only where they complete a real user task.
How It Works
Results use a documented ranking heuristic. It considers:
- Observed frequency where available – using the pinned frequency artifact
- Source and constraint fit – including exact pattern, letter, and list membership signals
Tiers and ordering describe this build's heuristic, not a universal judgement about English usage, game validity, or suitability for a particular puzzle. Some tools also suggest a bounded next filter based on the current result set.
Who Makes This
The Word Index is built and maintained by Matt Iles, a software developer and lifelong word-game player. Matt maintains the search engine and the review systems that record authorship, machine-generated analyses, contributors, and named human decisions for each piece. Individual guides and studies disclose their own author and review state rather than inheriting a claim from this biography. You can reach him through the contact page.
This is an independent product, not a programmatic article network. Public availability does not confer search eligibility: only pages with an explicit search approval enter the sitemap. How we build, review, and approve content is documented on our methodology page.
Our Data
Our compiled lexicon combines named, checksum-pinned artifacts and a versioned ranking heuristic. The configured sources do not all have approved reuse terms, so data-dependent pages remain excluded from search while that review is pending. See our Data Sources page for versions, checksums, licence evidence, and limitations, and our Methodology page for the build process.
Free to Use
The Word Index is free to use. Advertising may support the service when it is enabled; the Privacy Policy reports the current runtime state. The core lookup tools remain available without an account.
Privacy
We do not require an account. Searches are processed on our server, while application logs deliberately omit search terms, raw user-controlled paths, IP addresses, and user agents. Hosting and network providers still process connection data to deliver the site. Read our full Privacy Policy for details.
