Did you know?
     Commensal types, be they human or beast, often "break 
bread" together. When they do, they are reflecting the etymology 
of "commensal," which derives from the Latin prefix "com-," 
meaning "with, together, jointly" and the Latin 
adjective "mensalis," meaning "of the table." In its earliest 
English uses, "commensal" referred to people who ate together, 
but around 1870, biologists started using it for organisms that 
have no use for a four-piece table setting. Since then, the 
scientific sense has almost completely displaced the dining one.
