lucid

This term describes a state of transparency, whether it applies to a piece of writing, a mental state, or a physical light source. When describing communication, it suggests a quality of effortless clarity that removes ambiguity for the listener or reader. In medical or psychological contexts, it refers to a temporary return of sanity or consciousness. This specific usage often implies a fragile window of coherence amidst a broader state of delirium, dementia, or unconsciousness.
