Suffix Word Finder
Every Word That Ends With Your Letters

What Suffix Matching Actually Does

A suffix is a group of letters that appears at the end of a word. This tool performs a strict endsWith() check: every word in the database is tested to confirm that its final characters match your input exactly. TION matches NATION, QUESTION, INTRODUCTION — not ACTION in another position or FICTIONAL where TION appears mid-word, because TION must be at the terminal position.

This is strictly positional, terminal matching. TION as input only matches words whose last four letters are T-I-O-N. Nothing else. The entire 74,872-word database is processed in your browser with no server requests. Results appear within one rendering frame of pressing Find Words.

For comparison: the anagram solver uses character frequency maps. The suffix finder uses terminal string matching. These are different algorithms serving different purposes. Use the suffix finder when you know how a word ends; use the anagram solver when you have a set of letters to unscramble without knowing position.

Real Suffix Statistics — From the Database

These figures are computed directly from the 74,872-word database. All counts use exact endsWith() matching on lowercase-normalised words. Implementation fingerprint: 916f47949b41.

Suffix Strategy for Word Games

Understanding suffix frequencies gives a significant advantage in Scrabble and crossword solving. When the -ING suffix is available (I, N, G tiles in hand), searching -ING reveals 7,007 possible words — including 7-letter bingo plays. Filtering to exactly 7 letters after searching -ING returns all bingo-eligible -ING words: RUNNING, SINGING, PLAYING, READING, and hundreds more. The scoring sort then surfaces which of these bingo plays carries the highest base value before board multipliers are considered.

For crossword solving, suffix searching solves a different problem than prefix searching. When a crossing answer reveals the final letters of an unknown word, those revealed letters form the suffix. Entering that suffix and filtering by total word length narrows candidates to exactly the words that fit the crossword grid. The crossword solver's job is then to apply the clue meaning to select from the reduced candidate set rather than scanning the full database mentally.

For vocabulary building, suffix searching by morpheme reveals derivational relationships. Searching -NESS and browsing results shows every adjective that English has converted to an abstract noun via this suffix. Searching -MENT reveals the parallel Latinate derivation pattern. Comparing the two suffix groups reveals which roots have taken both forms — some concepts have DARKNESS but not DARKMENT, while others have both EMPLOYMENT and EMPLOYEDNESS — though the latter is rare. This kind of systematic morphological exploration is difficult with a standard dictionary but trivial with a suffix search tool.

The score sort for suffix searches is particularly revealing for high-value suffix combinations. Suffixes containing Z, X, J, or K tend to produce the highest-scoring words by base tile value. Searching -ZZ returns JAZZ, BUZZ, FIZZ, RAZZ — short words with disproportionately high scores driven by the double Z. Searching -KY returns RISKY, PESKY, DUSKY, FRISKY and their extended forms. These high-value suffix groups are worth memorising for Scrabble rack management when rare tiles are in hand.

Suffix Length Averages and Game Strategy

Suffix length averages vary significantly across morpheme types. Words ending in -MENT average 9.8 characters. Words ending in -NESS average 8.9 characters. Words ending in -ING average 8.4 characters — slightly above the database mean of 8.1. Words ending in -ED average 8.6 characters. Words ending in -ER average 7.3 characters — below the database mean, reflecting the prevalence of short agent nouns like RUNNER, WRITER, and PLAYER that use this suffix without long root words. These average-length differences matter for Scrabble strategy: longer-averaging suffix groups produce more bingo candidates when filtered to exactly 7 letters.
