CONVERSATION

n. talk, informal verbal exchange, discussion

Conversation is the verbalization of concepts involving abstractions and concrete objects which make up the world we live in.A conversation is communication by two or more people, or sometimes with one's self, often on a particular topic. Conversations are the ideal form of communication in some respects, since they allow people with different views of a topic to learn from each other. A speech, on the other hand, is an oral presentation by one person directed at a group.
