A formal language is an organized set of symbols the essential feature being that it can be precisely defined in terms of just the shapes and locations of those symbols. Such a language can be defined, then, without any reference to any meanings of any of its expressions; it can exist before any interpretation is assigned to it—that is, before it has any meaning. A formal grammar determines which symbols and sets of symbols are formulas in a formal language.

Famous quotes containing the words formal and/or language:
“The conviction that the best way to prepare children for a harsh, rapidly changing world is to introduce formal instruction at an early age is wrong. There is simply no evidence to support it, and considerable evidence against it. Starting children early academically has not worked in the past and is not working now.”
—David Elkind (20th century)
“My God! The English language is a form of communication! Conversation isn’t just crossfire where you shoot and get shot at! Where you’ve got to duck for your life and aim to kill! Words aren’t only bombs and bullets—no, they’re little gifts, containing meanings!”
—Philip Roth (b. 1933)
