astounded

This term describes a state of shock or overwhelming surprise that often leaves a person momentarily speechless or unable to react. It carries a much stronger emotional weight than "surprised" or "amazed," suggesting a sense of disbelief or a cognitive struggle to process an unexpected event.

While it can be used for positive revelations, it frequently appears in contexts of negative shock or sheer incredulity. Because it describes an internal emotional state, it is typically used as a predicative adjective following a linking verb, though it can precede a noun to emphasize the intensity of the subject's reaction.
