漏

• Physical leakage: Liquid escaping through a breach or gap; dripping. Usually implies an accidental or unwanted escape.
• Chronometry: The water clock (clepsydra). In administrative, courtly, or ritual contexts, refers to the instrument itself or the measurement of time by that instrument.
• Omission: To omit, leave out, or fail to include (e.g., a name missing from a list).

Contrast with 洩 (//xiè//): While both can be translated as "leak," //lòu// tends toward the passive, rhythmic, or accidental, whereas //xiè// more often implies a venting of pressure or the intentional revealing of a secret.

Be alert to the transition from "failure" (a leak) to "precision" (the clock). If the context is temporal rather than structural, the glyph likely refers to the clepsydra.
