The word "谈论" is formed by combining two individual characters, each contributing its core meaning to create a new, unified concept. The first character, "谈" (tán), inherently means "to talk" or "to converse". The second character, "论" (lùn), carries the meaning of "to discuss", "to discourse", or "to deliberate". When joined, they reinforce and slightly expand upon the idea of verbal exchange, resulting in a compound word that means "to talk about" or "to discuss", emphasizing a conversational or analytical dialogue on a topic.
