Chit-chats, also referred to as small talks, are commonplace and usually lead to an interesting conversation. However, when chit-chats lean towards the negative or gossipy, they can tend to become unpleasant. The antonyms for chit-chats include silence, reticence, and solemnity. Silence is the complete absence of any sound or conversation, and it is used when one wants to avoid unnecessary interruptions. Reticence refers to quietness and restraint when speaking, and is often used when one wants to avoid any misunderstandings or controversy. Solemnity, on the other hand, is a state of seriousness and gravity of the matter being discussed. It is used to convey emotional and formal aspects of the conversation.
