Key ideas in The Logic of Chinese Characters

  • Radicals as a taxonomic system
  • Radical as the genus
  • Shared conceptual roots
  • Left-side compression
  • Water radical mutation
  • Recognizing mutations
  • Categorizing characters into conceptual families
  • Structural adaptation and mutations
  • The standard structural layout for ~90% of characters is semantic-left, phonetic-right
  • Top-bottom characters usually place the semantic anchor at the top (e.g., 艹 for plants)
  • Radicals act as a taxonomic classification system
  • Identifying the left/top component first is the most reliable heuristic for guessing a new character's meaning
  • The 'meat' radical (肉) drifted over centuries to look identical to the 'moon' radical (月) in modern script
  • Recognizing compressed radical mutations
  • Characters related to body parts or organs almost always use the 'meat-moon' (⺼) variant
  • Contextual meaning is the only way to distinguish between these two historically distinct radicals in modern Chinese
