jaap
Jaap is a Dutch masculine given name. It is a diminutive form of Jacob or Jacobus and derives from the Hebrew Yaakov, meaning “holder of the heel” or “supplanter.” In the Netherlands—and to a lesser extent in Flanders—Jaap has long been used as an independent given name rather than only as a nickname, and it remains common across generations. The pronunciation is typically rendered as yaap, with a long “a.”
Notable people named Jaap include Jaap de Hoop Scheffer, a Dutch politician who served as Secretary General
Outside the Netherlands, Jaap is less common but appears within Afrikaans-speaking communities and among Dutch expatriates.
