What is the meaning of the name Katrijntje ?

Katrijntje is Dutch in Origin.

Katrijntje is a Dutch diminutive of Katrijn, a vernacular form of Catharina/Catherine. The -tje ending marks affection in Dutch, so “Katrijn” + “-tje” yields “Katrijntje,” often used as a standalone given name in Dutch-speaking regions. Its meaning aligns with Catherine’s widely accepted sense of “pure,” from association with Greek katharos, reinforced by Christian tradition surrounding Saints Catherine of Alexandria and Siena.

The name appears frequently in 17th–19th‑century records from the Netherlands and Flanders, sometimes as a formal baptismal name. Usage waned in the 20th century as shorter forms (Karin, Katrien) and international spellings gained favor; today it carries a rare, vintage Dutch charm. Related forms and variants include Katrijn, Katrien, Kaatje, Trijntje, Katelijne/Katelijn, Catharina/Katharina, Catherine/Caterina, Katarina, and Katrina. Common short forms are Kaat, Kat, and Trijn, with the near-identical spelling Katrijntje also encountered.
