闡

Core senses include explaining, clarifying, or elucidating. The underlying semantic sense is "making manifest" or "unfolding."

Almost exclusively a transitive verb. It typically takes abstract objects such as doctrines, laws, hidden truths, or points of contention. In very early texts, it may refer to the literal opening of a door. Frequently appears in compounds such as 闡明 (chǎn míng) and 闡發 (chǎn fā).

• vs. 釋 (shì): While 釋 typically implies interpreting or “untying” a specific knot of meaning, 闡 suggests a broader opening up—laying out a principle or unfolding a theory to make it visible.
• vs. 展 (zhǎn): Both share the sense of "opening/expanding," but while 展 refers to the physical or conceptual spreading out (e.g., a scroll), 闡 emphasizes the clarity and illumination resulting from that opening.

Simplified variant: 阐 (U+9610).

The glyph combines “door” (門) and “brightness/sun” (昜), suggesting the action of opening a barrier to let in light or reveal what was hidden. In older scripts, the 昜 component may appear similar to 日.

When the glyph stands alone, the imagery of "opening" and "revealing" is generally more potent than when it functions as part of a standard compound for "explain."
