The purpose of this article is to clarity the concept of two terms: Leisure and Recreation. Analyzing their definitions from related references, the author tried to use two approching, nonnormative and normative. The nonnormative way used five dimensions to interpret, there were time, activity, inner condition, purpose and outer condition, each dimension had two directions on one category. The normative way used functional and pratical viewes to provide the definition of both leisure and recreation in value orientation.
