Trivial conversation is often referred to as small talk or chit-chat. It's the casual, light conversation that we use to break the ice or fill in awkward silences. Other synonyms for trivial conversation could include idle talk, gossip, or banter. These are all words that describe the type of conversation that is not necessarily meaningful or important, but rather serves as a way to pass the time and connect with others. Some might also use words like chatter, prattle, or blabber to describe trivial conversation, which can sometimes be seen as excessive or unnecessary. Regardless of the word used, trivial conversation plays an important role in our social interactions and daily lives.
