What is Definition?
{{wiktionary|definition}} A '''definition''' in [[language]] explains what a [[word]] or [[phrase]] means. ''Defining'' means giving a definition. Other words with this meaning are ''[[wikt:description|description]]'' and ''[[explanation]]''. They describe what a word means and explains to the person when and where it can be used. In [[mathematics]], a definition is an exact way of saying what a mathematical concept is. It might not be the easiest way to say what it is, but it is used because it is exact. It can be used in a [[mathematical proof]]. {{-}} {{stub}} [[Category:Words]]
