極

• Concrete/Technical: A physical pole, pillar, or the axle-tree of a carriage.
• Spatial/Geographic: The furthest point, boundary, or the North Pole (including the North Star).
• Qualitative/Abstract: Extreme, utmost, final, or the highest degree of a quality.
• Ontological/Cosmological: In philosophical contexts (e.g., 太極), denotes the "Supreme Ultimate," acting as an ontological marker for primordial unity or absolute zenith rather than a measure of intensity.
• Administrative/Legal: Finality; the furthest extent of jurisdiction or authority.

• Noun: A pole, axis, boundary, or limit.
• Adjective/Adverb: Utmost, extreme; used to push a modified adjective to its logical conclusion.
• Verb: To reach the limit, exhaust (the extent of something), or push to the peak. In this role, it frequently implies a turning point where a state must either break or change direction.

Contrast with 盡: While both refer to "ends," 盡 typically denotes depletion, completion, or emptying out (exhaustion of resources). 極 denotes the arrival at a boundary or the attainment of a peak (attainment of a limit).

Simplified variant: 极 (U+6781).

The wood radical (木) anchors the glyph's lineage as "pole" or "axis."

In architectural or mechanical contexts, treat as a concrete noun before considering abstract meanings.
