form wiki:
>This article is about the meanings of the word form connected with shape or structure. For other meanings, see Form (disambiguation). Form (Lat. forma), in general, refers to the external shape, appearance, configuration of an object, in contrast to the matter or content or substance of which it is composed; thus a speech may contain excellent arguments (the matter may be good), whereas the style, grammar, arrangement (the form) may be bad. "Form is supposed to cover the shape or structure of the work; content its substance, meaning, ideas, or expressive effects." (Middleton 1999, p.141) The term, with its adjective formal and the derived nouns formality and formalism, is hence sometimes contemptuously used for that which is superficial, unessential, hypocritical: chapter 23 of Matthew's gospel is a classical instance of the distinction between the formalism of the Pharisaic code and genuine religion. With this may be compared the popular phrases good form and bad form applied to behaviour in society: so format (from the French) is technically used of the shape and size, e.g. of a book (octavo, quarto, etc.) or of a cigarette.
