Feijtje

Feijtje is a diminutive form of the Dutch name Feija, which itself is a short form of Sophia or other names ending in -fia. The 'tje' suffix in Dutch is a common diminutive, indicating 'little' or 'dear'. While Sophia means 'wisdom', the association with 'fairy' likely comes from a folk etymology or a playful interpretation of the sound, possibly influenced by similar-sounding words or the whimsical nature of diminutives.

The name is quite rare and has largely fallen out of common use. It reflects a historical naming practice in the Netherlands where longer names were often shortened and then given a diminutive suffix, creating unique and endearing forms. Its charm lies in its old-fashioned, quaint feel.
