Prolog vs. Lisp — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on September 22, 2023
Prolog is a logic programming language mainly used for symbolic reasoning and artificial intelligence. Lisp is a general-purpose, multi-paradigm language that excels in symbolic computing and is known for its parentheses-heavy syntax.

Key Differences
Prolog and Lisp are both programming languages, but they differ significantly in their paradigms and primary uses. Prolog is a declarative language that is particularly strong in logic-based computation and symbolic reasoning. It works based on facts and rules, aiming to solve problems by searching through potential solutions.
Lisp, on the other hand, is known for its flexibility and is more of a general-purpose language. It is designed to support multiple programming paradigms, including functional and procedural styles. Lisp is often used for artificial intelligence, machine learning, and natural language processing, although its applications are much broader.
While Prolog's syntax is more focused on predicate logic, Lisp's is characterized by its frequent use of parentheses, which define both the code structure and data format. This makes Lisp highly extensible, allowing users to create new functions and syntax easily.
Prolog tends to be used more in specialized fields like expert systems, natural language processing, and theorem proving. Lisp, meanwhile, has a broader range of applications and is often utilized in complex systems requiring adaptability and extensibility.
In summary, Prolog specializes in logic-based computations and rule-based problem solving, whereas Lisp is a versatile language that accommodates various programming paradigms. Both have made significant contributions to the field of artificial intelligence but are tailored for different types of projects.

Prolog
Prolog is a logic programming language associated with artificial intelligence and computational linguistics.Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program logic is expressed in terms of relations, represented as facts and rules. A computation is initiated by running a query over these relations.The language was developed and implemented in Marseille, France, in 1972 by Alain Colmerauer with Philippe Roussel, based on Robert Kowalski's procedural interpretation of Horn clauses.Prolog was one of the first logic programming languages and remains the most popular such language today, with several free and commercial implementations available.
Lisp
A lisp is a speech impairment in which a person misarticulates sibilants ([s], [z], [ts], [dz], [ʃ], [ʒ], [tʃ], [dʒ]). These misarticulations often result in unclear speech.
Prolog
An introduction or preface, especially a poem recited to introduce a play.
Lisp
One of the first high-level programming languages, designed to handle complex data structures. It is widely used in artificial intelligence research.
Prolog
An introduction or introductory chapter, as to a novel.
Lisp
A speech defect or mannerism characterized by mispronunciation of the sounds (s) and (z) as (th) and (th).
Prolog
An introductory act, event, or period.
