You typed a perfectly good English word, pressed ENTER, and the game refused it. Annoying? Yes. A bug? No. Every Wordle checks your guesses against a dictionary — and the dictionary’s rules explain almost every rejection. Here is how it works, on our site and in the game generally.
The two lists: answers versus acceptable guesses
The single most important thing to understand is that Wordle runs on two separate lists:
- The answer list — the words that can be today’s solution. Kept small and curated: common, pleasant, non-offensive words.
- The guess list — every word the game will accept as a guess. Much larger, because a guess does not need to be a plausible answer; it only needs to be a legitimate probe. Obscure words, plural forms and unusual verbs live here.
Every word on the answer list is automatically also on the guess list. The reverse is not true — and that asymmetry is the source of most confusion. A word can be a legal guess and still never be the answer.
How our dictionary works
The daily puzzle on our homepage uses a deliberately compact, curated dictionary:
- 30 answer words — the daily rotation. Friendly, high-frequency five-letter words: PLANT, CRANE, SHINE, LIGHT, DREAM, BLOOM, CLOUD, PEACH, SMILE, BRAIN and their peers. One word serves each calendar day, chosen by the date, so every visitor gets the same puzzle on the same day.
- 446 additional accepted words — common five-letter words you may use as guesses: ABOUT, ABOVE, ACTOR, ADMIT, AFTER, AGAIN and so on.
- 476 words total. If your guess is not among them, you will see the message: “Not in this demo’s word list. Try another common word.”
Why so small compared to the thousands of words in bigger implementations? By choice. A compact list keeps the puzzle fair, keeps the vocabulary approachable, and matches what this site is for: a calm daily ritual, not a dictionary exam. The trade-off is real — occasionally a word you know is rejected here but accepted elsewhere — and the next section explains both why that happens and what to do about it.
The five reasons a real word gets rejected
1. It is a proper noun
Names of people, places, brands — PARIS, JAMES, SONY — are excluded from Wordle dictionaries almost universally. The game tests spelling and letter logic, not geography.
2. It is a plural or conjugated form — depending on the game
Original Wordle’s answer list famously excluded plural forms ending in S (and most past-tense -ED forms) as answers, because plurals are unfair: WORDS and WORDL look identical until the last letter, and one of them is a pure coin flip. But many implementations still accept plurals as guesses. Rule of thumb: plural of the answer-list, fine to guess; rarely the answer.
3. It is archaic, dialectal or slang
Valid Scrabble monsters — words with no vowels, two-letter compounds, Scottish dialect terms — are exactly the kind of entries one list includes and another omits. Dictionary curation is editorial, and different curators draw the line differently.
4. It is offensive — by design
After acquiring Wordle, The New York Times removed a batch of crude and slur-adjacent terms from both lists. Any well-kept word list today has a decency filter. If a rude word “mysteriously” fails, that is the filter working.
5. It is simply not on this site’s list
Our 476-word dictionary covers the common core of English five-letter words, not the whole language. A legitimate word like a rare VERBS-family form or an unusual noun may fall outside it. Nothing is wrong — the game is telling you, honestly, that its list is curated.
What to do when you are rejected
A rejection costs you nothing — the message appears, your board is untouched, no guess is consumed. So the strategy is simple:
- Try the most common variant. If TEALS fails, try STEAL or TALES. Wordle answers love anagrams of each other.
- Prefer dictionary-frequent words. The words most likely to be accepted are the ones most likely to appear in a newspaper. That heuristic fixes most rejections in one step.
- Use the rejection as information. On strict lists, a rejected guess also tells you that word is not the answer — one candidate fewer for later turns.
- Never waste two guesses on the same gamble. If an unusual word was rejected once, assume the list will not suddenly grow.
How big are the famous word lists?
For scale — and because these numbers explain the “difficulty” reputation of different versions:
- Original Wordle (2021): about 2,315 answer words and roughly 10,000 additional acceptable guesses.
- The New York Times version (today): the answer list is now hand-curated (harder and stumpier words on purpose), while the accepted-guess list was expanded to well over ten thousand entries — including many plurals and oddities, precisely so that exploring guesses rarely gets blocked.
- Our site: 30 rotating answers, 476 accepted words, optimized for approachability over coverage.
The practical consequence: the bigger the accepted list, the more freedom you have to run exotic “burner” guesses that test rare letters; the smaller the list, the more you should stick to common words both as guesses and as candidate answers.
Word-list trivia that wins games
- S is the most common final letter — but on strict lists, S-endings are mostly guess-only. Do not burn turn five on a plural.
- E is the most common answer letter overall, and it loves the fourth and fifth positions — GREEN, SWEET and SHINE all prove the point on our own board.
- Answers skew friendly. Curated answer lists (ours included) favor words people enjoy saying. If your candidate sounds like a tax form, it probably is not the answer.
Where to go next
Word-list logic pairs naturally with the counting rules in Repeated letters: how Wordle really counts them, and with the opener science in Best starter words. Or simply put it into practice: today’s puzzle is on the homepage — and if a guess gets rejected, now you know exactly why, and exactly what to try instead.
