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
