Changes: retained the game's existing word set, normalized explicit POS, attached direct synset relations and source-declared inflections, compressed for client use. Separately versioned AI-reviewed annotations add selected Chinese translations and question distractors; these are project edits, not original WordNet text or teacher certification.
Machine compilation is not teacher review. Historical tags and source order are not current usage-frequency measurements. Chinese and English arrays are not aligned.
