際

The glyph denotes an interface—the specific point or thin margin where two distinct entities, spaces, or time periods touch. This includes:

1. Spatial: A border, frontier, or rim; the edge of one thing that is simultaneously the edge of another.

2. Temporal/Situational: A specific moment, occasion, or juncture ("at the time when," "on the occasion of").

• Noun: The physical or metaphorical boundary.
• Situational Marker: Used to frame a circumstance; specifically in the construction 際於... to pin an action to a specific time or place.
• Pivot/Prepositional use: Serves to set the scene ("At this juncture..."), acting as a marker of condition or timing.

[DISTINITIONS]

• 際 vs. 界 (jiè): 界 emphasizes division, category, or a rigid separating line; 際 emphasizes the contact point or seam.
• 際 vs. 邊 (biān): 邊 refers to the side, outskirts, or general periphery; 際 focuses on the precise point of intersection.
• 際 vs. 限 (xiàn): 限 denotes a limit or restriction where something must stop; 際 is the point where one thing begins and another ends.

Simplified variant: U+9645.

Avoid projecting the modern geopolitical sense of "international" (國際) back into ancient texts. In early classical Chinese, the glyph typically refers to a physical edge or a specific moment in time rather than relationships between nation-states.
