, as participants in emotionally-charged exchanges will sometimes become more concerned about swaying people to one side or another than expressing the unbiased facts.

Overview and example

Language can simultaneously communicate information (informative) and feelings (expressive). Unlike other common types of definitions in logic, persuasive definitions focus on the expressive use of language to affect the feelings of readers and listeners ultimately with an aim to change their behavior. With this fundamentally different purpose, persuasive definitions are evaluated not on their truth or falsehood but rather on their effectiveness as a persuasive device.

Patrick Hurley provides a number of examples of contentious terms with two opposing persuasive definitions, among them a favorable and unfavorable definition of taxation:
  • definition supporting taxation: "the procedure by means of which our commonwealth is preserved and sustained"
  • definition opposing taxation: "the procedure used by bureaucrats to rip off the people who elected them"


Neither definition is particularly informative compared to a commonly accepted lexical definition
Lexical definition
The lexical definition of a term, also known as the dictionary definition, is the meaning of the term in common usage. As its other name implies, this is the sort of definition one is likely to find in the dictionary...

. Note how the supporting view uses positive language where the opposing view uses negative language, such as the word bureaucrat which carries an unfavorable connotation alongside its informative meaning.

Unclear, figurative language is often used in persuasive definitions. Although several techniques can be used to form such a definition, the genus and difference technique is the usual one applied. Both definitions in the taxation example above agree that the genus is a procedure relating to governance but disagree on the difference. Persuasive definitions combine elements of stipulative definition
