speechless

This term describes a state of temporary or permanent silence. When applied to humans, it usually conveys a sudden emotional paralysis where the intensity of a feeling—such as awe, horror, or indignation—overwhelms the capacity to formulate words. It suggests a gap between internal experience and external expression. In a biological or developmental sense, it refers to the inherent lack of linguistic capability. This usage is descriptive and neutral, distinguishing beings that cannot communicate via spoken language from those that can.
