Confluence
A confluence is the merger or meeting of two or more objects (or subjects) that seem to inseparably bind their respective forces or attributes into a point of junction.The word is typically used in geography to describe the point where two rivers meet and become one, usually when a tributary joins a more major river.
The word is comprised of the prefix con (from the Latin "com"), meaning "with" or "together", and joined with the suffix fluence from the Latin "fluere" meaning "to flow". The resulting meaning literally translates as "to flow together". It is interesting to note that the joining of both prefix and suffix to make the word confluence is a confluence in and of itself; both word parts join to form something that flows in the phenomenal river of language.
