Why was my word rejected in Chainle?

Short answer: Chainle only accepts a single English word of 2-28 letters with no spaces, hyphens or punctuation, and the word must exist in the game's vocabulary; entries outside it do not use up your turn.

A rejected entry almost always comes down to one of the word rules. Chainle’s input is strict about format, and it also relies on an internal vocabulary list.

Even a correctly formatted entry can be declined if the word is not in the game’s vocabulary. The vocabulary supports common word forms and selected British and American spellings, but rare, highly technical or very obscure words may not be recognized.

The important consolation: an entry outside the vocabulary does not use up your turn. You simply try another word at no cost, so a rejected guess is never a wasted round. If you keep hitting rejections with unusual spellings, switching to the more common form usually solves it.

The word rules page documents every constraint in detail, and the bridge word glossary entry explains what kind of word you are actually looking for.
