節

• Structural & Physical: Nodes, joints, or knots (botanical/anatomical); segments or distinct sections of a larger whole.
• Regulatory & Normative: Measure, limit, proportion, and restraint; standards, protocols, or ritual benchmarks; moral integrity or constancy.
• Temporal & Cyclical: Intervals marking transitions; solar terms (節氣) or seasonal divisions; festivals and designated occasions of observance.

• Noun: A joint; a section; a regulation/standard; a season/festival.
• Verb: To regulate; to limit; to economize (e.g., 節省); to articulate or divide into sections.
• Adjective/Adverbial: Measured, moderate, disciplined, or proportional.

• Articulation vs. Restriction: In philosophical or cosmological contexts, the term often denotes an "articulation"—a necessary limit that enables sustainable growth and circulation—rather than a simple prohibition or hindrance.
• Functional Division: Distinct from terms meaning rupture; it refers to a functional division that preserves the integrity of the whole rather than a break that destroys it.
• Ritual Contexts: May refer either to the objective standard being followed (the rule) or the subjective virtue of following it (moderation/discipline).
