Palaverer is a noun that means a person who talks at length about trivial matters. Synonyms for palaverer include chatterbox, motor-mouth, blabbermouth, conversationalist, talkative person, gossip, and windbag, among others. These terms often imply that the person speaks too much or too often, possibly wasting time and energy. Some may also suggest that the person's speech is not always meaningful or relevant to the situation. However, it's important to note that being talkative is not necessarily a negative trait, and in certain situations, such as socializing or networking, it can be an asset. The choice of synonym depends on the context and the intended tone.
