積

Incremental addition through layering or stacking (originally associated with grain).

• Concrete/Physical: Stockpiling resources; a heap, hoard, or granary.
• Abstract/Temporal: The gradual build-up of non-physical entities over time, such as virtue and merit, faults, or the sum of years and experience.

// Technical/Mathematical: In administrative or mathematical contexts (e.g., //The Nine Chapters on the Mathematical Art*), a calculated total; used for area, volume, or the product of multiplication.

Functions as a verb (to accumulate), a noun (a stockpile or numerical sum), or a modifier (e.g., "accumulated").

Contrast with 聚 (//jù//): //jù// implies convergence toward a center, whereas 積 emphasizes verticality and layering. Contrast with 儲 (//chǔ//): //chǔ// emphasizes the intent to save for future use, whereas 積 emphasizes the resulting mass or volume.
