Tjeerd is a masculine given name of Theodoard or Theodard, two Germanic names composed of the elements theod meaning "people" (from Old High German diota or Old Frankish þeoda) and wart meaning "guard, guardian." Thus, the name carries the sense of "guardian of the people." Etymology and History The name Tjeerd is particularly common in the Netherlands, especially in the province of Friesland, where Frisian names have a strong presence. It is a West Frisian form that underwent regular sound changes from the original Germanic Thiadward or Theodoard, with the initial Th becoming T and the medial vowels shifting. Variants include Tjaard and Dieuwert, while the diminutive Dieuwe and the feminine Dieuwke also stem from the same root. In other cultures, cognates include German Diethard and Afrikaans Tjaart.
