蔽

• Physical: To cover, shield, or screen. This ranges from positive protection (shelter) to neutral shielding (e.g., a canopy or veil). As a noun, it refers to the object providing the cover (a screen or obstruction).
• Concealment: The act of hiding or obscuring. In administrative, legal, or political contexts, this typically implies an intentional effort to hide a flaw, crime, or truth from a superior or the public.
• Cognitive/Perceptual: To blind or cloud. When applied to the eyes (目) or the mind, it denotes a failure of perception; judgment is obstructed by an external or internal "screen"—such as prejudice, flattery, greed, or affection—preventing the subject from seeing reality clearly.

• Transitive Verb: To cover; to hide; to deceive (by obscuring).
• Intransitive/Stative: To be blinded; to be obscured; to be sheltered.
• Noun: A screen, covering, or obstruction.

Distinguish from 敝 (bì, "worn out/shabby"). In cursive or weathered manuscripts where the grass radical (艹) is poorly rendered, context is the primary decider: determine whether the passage implies obstruction (蔽) or dilapidation (敝).
