The phrase 无话可说 (wú huà kě shuō) is formed through a logical and common grammatical construction in Chinese, combining negation, object, and potentiality. It begins with the negator 无 (wú, "without" or "to lack"), which directly governs the noun 话 (huà, "words" or "speech"). This forms the core idea of "having no words". This core is then modified by the potential complement 可说 (kě shuō, "can be said"), where 可 (kě) indicates possibility and 说 (shuō) is the verb "to speak". Thus, the entire structure literally parses as "without words that can be spoken", and by idiomatic extension, it means "to have nothing to say", often conveying a sense of speechlessness due to helplessness, frustration, or complete agreement.
