644: Dialog and Conversation Sep 12, 2016

There are a number of ways to think of speech between two people. Syntactically, one can "talk to" or alternatively "talk with" someone. There is a great deal of debate about the meaning of the prepositions in those senses, but they can be used fairly interchangeably. Not only that, but there is 'conversation' 'dialog' that exists between 'interlocutors'. Are three of those words in quotes use prepositions from Latin; the first, 'con-' means 'together/with', and last, 'inter-' means 'between'. Not only that, but 'dia-' means 'through' and although it does have a variant 'di-', the sense of 'di-' as 'two' is not so connected to the meaning.
