Jyll Origin and Meaning

The name Jyll is a girl's name.

Jyll is a feminine name representing a modern, streamlined spelling variant of Jill. The traditional Jill derives from the medieval nickname for Julia or Gillian, which ultimately comes from the Latin Julius, meaning 'youthful' or 'downy-bearded.' This contemporary spelling with the double 'l' and 'y' substitution emerged as parents sought distinctive ways to update classic names. Jyll maintains the short, spunky appeal of Jill while offering visual uniqueness on paper. Though relatively uncommon, it peaked in usage during the 1970s and 1980s when alternative spellings became fashionable. The name carries connotations of youthfulness and playfulness with its bright, compact sound.
