Jannik

Jannik is a Danish masculine given name, functioning as a diminutive form of Jan, which itself derives from the Hebrew name Yohanan, meaning God is gracious. The name follows a common Scandinavian pattern of forming pet names by adding the suffix -ik to a shorter base form. It is well attested in Denmark and has gained broader international recognition through Danish tennis player Jannik Sinner, though Sinner is Italian, while the name itself remains most closely associated with Danish naming tradition. Related forms include Jan, Johan, Johannes, and the German diminutive Jannik shares ground with Hannick and similar northern European variants.
