ABSTRACT
A conversation is an informal interaction involving two or more participants, differing: (a) from a dialogue, which is more formal (as between representatives of the parties to negotiations); (b) from a discussion in a seminar or in a committee meeting, in which agreed rules of procedure are followed; (c) from a talk, presentation or lecture, in which one speaker addresses an audience and may welcome or invite comments and answer questions; and (d) from an interview in which the participants are either interviewing or being interviewed.
