Syn. -- Intercourse; communion; commerce; familiarity; discourse; dialogue; colloque; talk; chat. -- Conversation, Talk. There is a looser sense of these words, in which they are synonymous; there is a stricter sense, in which they differ. Talk is usually broken, familiar, and versatile. Conversation is more continuous and sustained, and turns ordinarily upon topics or higher interest. Children talk to their parents or to their companions; men converse together in mixed assemblies. Dr. Johnson once remarked, of an evening spent in society, that there had been a great deal of talk, but no conversation.
