A '''programming language''' is an artificial [[language]] used mainly for giving instructions to [[computer]]s; a secondary use is for the precise specification of [[algorithm]]s. A group of instructions for a particular purpose is known as a [[computer program]].  

When compared with human languages (e.g. English, French, Spanish, etc.), programming languages are very much smaller, much simpler, and are also more precise.  Most programming languages consist of a mixture of English words and mathematical notation; very few programming languages have a base vocabulary exceeding 60 words, although they may also have utility libraries with hundreds of entries which provide optional extra functionality.
