MORE ABOUT FORMAL LANGUAGE
What is formal language?
A formal language is a language designed for use in specific situations, such as math or computer programming.
A natural language is a language that has been developed naturally over time by its users. We use natural languages, such as English, Spanish, Hindi, and Japanese, to communicate with each other. Natural languages constantly change and evolve.
Formal languages, on the other hand, are planned and designed. They are created to serve a specific purpose and, as a result, have very strict rules from the beginning. They often use symbols, numbers, and characters that natural languages do not. You’ll find formal languages used most often in mathematics and computer programming.
A formal language does have some things in common with a natural language:
- A formal language has an alphabet. For example, math uses specific symbols and characters (such as, 1, a, +, =) in the same way that English uses specific letters. Rather than “words,” formal languages use their alphabets to form strings.
- A formal language has syntax, meaning that the order and placement of strings matters. If the syntax isn’t followed, you get nonsense. For example, “2+2=4” is acceptable according to the syntax of math whereas “1-=+%32” is not.
- A formal language has semantics. That is, the strings have specific meanings. Just as top and pot mean different things in English, “2-x” and “x-2” have different meanings in math. Similarly, we know that in math the symbol “+” and the symbol “-” have different meanings.
However, while natural languages tend to have a lot of ambiguity and redundancy, formal languages do not. For example, the symbol “H” in chemistry means “hydrogen” and never anything else. Formal languages mean exactly what they say.
Why is formal language important?
The first records of formal language, meaning a contrast to a natural language, come from around 1926. The philosophy and theory behind formal languages is thought to be older and is often traced back to the work of mathematicians Gottfried Leibniz (1646–1716).

It is often thought that the first formal language was created by mathematician Gottlieb Frege, in his book Begriffsschrift (1879). In the book, Frege unsuccessfully attempted to create a formal language that proved mathematics could be reduced to logic.

Our #ICLR2020 paper "Program Guided Agent" is accepted as a spotlight paper! We propose a modular framework that can accomplish tasks specified by programs, structured in a formal language, and achieve zero-shot generalization to more complex tasks.
