Why your word was rejected
Every word game has a dictionary. Every dictionary is wrong about something.
The two reasons a word is refused
A guess can fail at two different points. The first is the dictionary: the word you typed is not on the accepted list. The second is the step rule: the word is listed, but it does not change exactly one letter from the rung before it. Those are separate checks, and they produce the same short refusal on screen. The two checks exist for different reasons, and only one of them is about the size of the dictionary. It helps to know which one you hit. If the word is plainly common and the right length, compare it with the previous word letter by letter. If it differs by one letter and still fails, the list is the obstacle. A refusal does not mean the word is not English.
The list is small on purpose
Rung a Day uses about 2,300 common four-letter English words. That is a deliberate limit, not an attempt to catalogue the language. A daily puzzle has to be shared: the same words for every player, and no account is needed. A compact list of familiar words keeps the search space legible and keeps the answer within reach without specialist knowledge. It also makes par meaningful, because the shortest route is computed over exactly the words everyone can use. The list does not settle arguments about what English includes; it defines the ground the puzzle runs on. The cost appears whenever a word you know is turned away. No fixed list can include every word that feels ordinary to somebody.
Proper nouns and dialect are left out
Two categories cause much of the frustration. Proper nouns are names of people, places and brands, and they are rejected even when they are four letters long and familiar. Dialect words are rejected too, including regional forms that are standard where you live but not part of general English. The reasoning is consistency: if a name or a local variant were allowed, the accepted vocabulary would depend on where a player grew up or which names they happen to know. Leaving both out keeps the list neutral, though it also means some perfectly real words never appear. That boundary is consistent, but it is not invisible to the player who typed the word. The trade is a shared vocabulary that narrows what counts as fair.
Why a huge dictionary hurts
Adding more words sounds like an obvious improvement. In a word ladder it changes the puzzle itself. Par is found by exhaustive search, so every added word can create a new shortcut between rungs that were previously far apart. Every extra entry widens the search space, and the shortest route can move without warning. A larger list can make shortest routes depend on obscure terms, and a player who does not know those terms is stuck for reasons unrelated to skill. It also makes the daily puzzle harder to keep consistent, because one addition can change the best route for any puzzle that touches it. A smaller list is easier to explain and easier to trust. It will still be wrong about some words, and that is the honest limit of the format.
Questions
Why was my common word rejected?
Check the step first. If the word changes exactly one letter from the previous rung and still fails, it is outside the accepted list. That can happen to familiar words, because a fixed vocabulary cannot match every player's English.
Does the game accept every real word?
No. The list is limited to about 2,300 common four-letter words, and obscure words, dialect words and proper nouns are excluded on purpose. A word can be real and still be outside the list, so a refusal is not a claim that the word does not exist.
Why not use a larger dictionary?
A larger dictionary adds shortcuts. Par is found by exhaustive search, so extra words can change the shortest route and make the answer depend on obscure terms. The smaller list keeps the daily puzzle shared and the routes easier to follow.
