Church or enclosure
Kirt is a variant of the name Kurt or Curt, often serving as a diminutive of Curtis or Konrad. It is derived from the Germanic word for 'court' or 'enclosure,' or the Greek word for 'lord' via the word for 'church.' In American usage, it is a rare mid-century variation that has largely fallen out of favor.
