曠

• Spatial: Broad, extensive, or wide; often carries a connotation of vacancy or desolation.
• Temporal/Behavioral: To waste time; to procrastinate (e.g., 曠日).
• Functional/Administrative: To leave a post vacant; to neglect a duty or obligation.

• Adjective: Describing physical space as vast/empty, or describing a state of vacancy.
• Verb: The act of neglecting a duty or wasting time.

• vs 空 (kōng): While both mean "empty," 空 is the generic term for void; 曠 implies a scale or breadth that makes the emptiness significant, daunting, or desolate.
• vs 廣 (guǎng): While 廣 often denotes positive expansiveness (e.g., broad knowledge), 曠 leans toward the void or the unused.

• Simplified variant: 旷 (U+65F7).

Determine if the context describes a physical landscape (vastness/desolation) or a behavioral failure (neglect/procrastination); the transition from "wide open space" to "wasted time" is a primary semantic shift in classical usage.
