Words With No Repeated Letters

How many five-letter words use five different letters

Rather more than people expect. A clear majority of five-letter English words contain no repeated letter at all, which makes the repeated-letter words the exception rather than the rule, and explains why they are so easy to overlook.

This page is the complete set of the majority case: every five-letter word in which each letter appears exactly once.

What makes this set structurally different

Words without repeats have to distribute their consonants and vowels more evenly, because there is no way to lean on a doubled letter to fill a slot. That pushes them towards the consonant-vowel-consonant-vowel-consonant shape and its close variants.

The practical consequence is that this list is unusually rich in words with two separated vowels, and unusually poor in the -LL, -SS and -TT endings that account for a large share of English five-letter words generally.

Why the distinction is useful

If you are filling a five-letter slot and you know two of the letters are the same, this list is precisely the set to exclude. If you know all five are different, it is the set to search. Either way, splitting five-letter words along this line cuts the search space roughly in half at no cost.

It is also the right list when you want a word that tests as many distinct letters as possible, such as a guess in a clue-based puzzle, or an opening play that touches the most new tiles.

Letters that resist appearing here

A few letters are underrepresented for structural reasons. S is common in five-letter words largely as a plural ending, and plurals of four-letter words frequently repeat a letter from the stem. Words built on double consonants drop out of this list entirely.

Q is nearly absent for a different reason: it almost always drags a U with it, which consumes two of five slots and leaves little room to place three more distinct letters that form a word.

Using the list against a filter

Reading a list this long start to finish is not the point. Use your browser's find function for a letter pattern you are working with, or put your constraints into the solver, which filters the same word list against fixed positions, required letters and excluded letters at once.

About this list

Five-letter words with no repeated letter, from the standard English word list this site uses throughout. It includes archaic and uncommon entries as well as everyday vocabulary.

5,665 Words, Five Unique Letters Each

These words never repeat a letter, which makes them efficient opening guesses -- every letter you type tests a different part of the alphabet instead of wasting a guess on a duplicate.

Two Thirds of All Five-Letter Words Are on This List

5,665 of the 8,636 valid five-letter words use five different letters. That is 65.6 percent, which reframes what this page is for. It is not a list of unusual words. It is the ordinary case, and the roughly one third of words that repeat a letter are the exception.

That number is the single most useful thing to carry into a puzzle, because it tells you how to weight a decision you make several times a game. When you are stuck and wondering whether the answer doubles a letter, the honest prior is about one in three. Not negligible, and not the first thing to reach for either.

It also explains why openers are built from this list. Any guess that repeats a letter wastes a slot: you learn about four letters instead of five. That is a real cost on your first guess, when information is everything, and it is why every strong opening word uses five distinct letters.

When to Suspect a Repeated Letter

Because the base rate is one in three, you should not guess a doubled word early. You should reach for it when the evidence points that way, and there are three specific signals.

You have four greens and nothing fits. If you have confirmed four positions and the remaining slot has no candidate among the letters you have not tried, the answer almost certainly repeats one of the letters you already have. This is the most reliable signal there is.

A letter came back yellow twice. If your guess used a letter in two positions and both came back yellow, the answer contains that letter at least twice. That is definitive, not a hint, and a surprising number of players read it as a single displaced letter.

You are in a -LY, -RY, or -SS shape. Certain endings carry doubled consonants far more often than the average word. CARRY, MARRY, WORRY, SORRY, HAPPY, FUNNY, and their relatives all live there. If you have a confirmed Y at the end and single consonants keep failing, check the doubles.

The Grey That Is Not a Grey

This is the rule that separates a solver that works from one that quietly discards the right answer, and it is worth understanding even if you never open a tool.

Suppose the answer is SPEED and you guess ERASE. Your first E comes back yellow. Your second E comes back grey. That grey does not mean the word has no E. It means the word has no E beyond the ones already accounted for by the coloured copies.

Naive filters treat every grey as a blanket exclusion, which throws SPEED out of the candidate list entirely. The solver on this site counts occurrences rather than treating a letter as simply present or absent, so a letter marked once yellow and once grey is read as exactly one of that letter.

Given that a third of five-letter words repeat a letter, this situation comes up constantly, and it is the most common way a player ends up convinced their puzzle has no solution.

Using This List as an Opener Reference

The reason to browse a list of five-distinct-letter words is to build openers, and the criteria are simple.

Cover common letters. Across the whole word list, S appears in 4,001 words, E in 3,881, A in 3,495, R in 2,670, O in 2,533, and I in 2,429. A word drawing from that pool tests more of the answer space per guess than one built on rare letters.

Spread the vowels. Two vowels in a five-letter opener is the sweet spot. One tells you too little about the vowel structure, three costs you a consonant slot in exchange for information about a case that only occurs in about one word in ten.

Discount the trailing S. Almost a third of five-letter words end in S because English pluralises freely, but curated daily puzzles strip most plurals out of their answer lists. An opener that spends position five on an S is testing a letter that is over-represented in the dictionary and under-represented in the answers.

Have a second opener ready. A prepared pair of words that between them cover ten distinct common letters will resolve most puzzles into a handful of candidates by guess two, which is a better use of preparation than optimizing the first word alone.

Working From What You Have

5,665 words is not a list to read. Use your browser's find function for a fragment you have already confirmed, or hand every constraint to the solver, which applies greens, yellows, and greys to the full list in a single pass.

Enter the greys. Players record the coloured tiles and skip the blank ones, which is backwards: five eliminated letters typically cut the field by more than half, often a bigger reduction than a single green delivers.

And when the solver returns a long list, resist guessing from it at random. Look at what varies among the candidates and pick a guess that splits that variation, even if the guess could not be the answer. One probe that halves the field beats five guesses that eliminate one word each.
