Jaakko

Jaakko is the Finnish form of Jacob, ultimately derived from the Hebrew name Yaakov, meaning "holder of the heel" or "supplanter," referring to the biblical patriarch who grasped his twin brother Esau's heel at birth. The name has been a common masculine given name in Finland for centuries, strongly associated with the feast day of Saint James in the Lutheran calendar. Closely related forms include the Finnish variant Juhana-derived Jaako, as well as the broader family of European cognates such as Jakob, Jacques, James, and Diego, all tracing back to the same Hebrew root.
