The word 说话 (shuōhuà) is formed by combining two independent characters, each contributing a core meaning to create a new, unified concept. The first character, 说 (shuō), represents the action "to speak" or "to say". The second character, 话 (huà), represents the object or content of that action: "words", "speech", or "language". When placed together, they conceptually merge the act of speaking with the substance of speech, forming the complete idea of "to talk" or "to speak". It is a logical pairing where an action is naturally linked to its fundamental object.
