Why can Poople reject a real word?
A word can exist in an English dictionary and still be unavailable in a particular word game. Poople checks guesses against its own curated list. Words may be excluded because they are rare, inflected, abbreviated, proper names, or simply absent from the version of the list currently used by the game.
This checker says whether a spelling appears in the synchronized public game data. It does not label rejected entries as “not English,” and it does not add words from a separate dictionary.
Accepted word vs. legal move
These are two separate checks. First, the new word must appear in the accepted list. Second, it must differ from the current word in exactly one position. For example, POOL → POOP is legal because only the last letter changes. COOL → POOP is not a single legal move because two positions change.
How the checker works
- Normalize the spelling. The checker converts the entry to uppercase and only accepts four letters.
- Look up the current list. The spelling is compared with the public word data synchronized from the game.
- Find one-letter neighbors. Every possible single-position substitution is checked against that same list.
- Measure the distance. For accepted words, the precomputed word graph reports the minimum number of moves remaining to POOP.
