[CM: A formal language consists of an alphabet that defines permissible symbols (characters, glyphs or marks) and a set of rules for formation of terms from the symbols and expressions from the terms (syntax). It will also have a semantics that maps particular symbols or terms to precisely-defined concepts (e.g., the familiar rectangle used to represent a class in UML, or the use of an inverted a tilde “” to signify negation).
