The word 实话 is formed by combining the character 实 (shí), meaning "real", "true", or "solid", with the character 话 (huà), meaning "speech" or "words". It is a conceptual compound where the first element directly describes the quality of the second, resulting in the core meaning of "true words" or "real speech". This formation creates a single, unified concept, truthful statement, where the adjective-like 实 modifies the noun-like 话 to specify a particular, fundamental category of speech.
