Formalist film theoryThe Formalist film theory identified the basis of Hollywood narrative construction, called the Institutional Mode of Representation.	Formal languageIn mathematics, logic and computer science, a formal language is a set of finite-length words (i. character strings) drawn from some finite alphabet, and the scientific theory that deals with these entities is known as formal language theory''. Note that	Formal grammarIn computer science a formal grammar is an abstract structure that describes a formal language precisely, i. a set of rules that mathematically delineates a (usually infinite) set of finite-length strings over a (usually finite) alphabet.

For example, formal logic reasons about a logical argument based only on the form and not on the meaning.
