These fourteen words are the same concept set worldwide: abstract, academic, and tight forbidden lists. One shared hard deck—only the surface word changes per language.

• Abstract and multi-meaning (paradox, entropy)—near synonyms are often taboo.
• Science / philosophy / art terms (dialectic, surrealism)—obvious clue words are blocked.
• Sound simple but resist clean descriptions (empathy, platonic).
