par·kour (pär-kōōr') n. A sport or athletic activity in which the participant seeks to move quickly and fluidly through an area, often an urban locale, by surmounting obstacles such as walls and railings and leaping across open spaces, as in a stairwell or between buildings.
[French, from respelling of parcours, distance covered, course, from Old French, right to drive or pasture animals in an area, route, from Medieval Latin percursus, from past participle of Latin percurrere, to run through, rove; see percurrent.]
