Thin meadow or hedge meadow
Tinlee is a modern American coinage, likely a variant of names like Tenley or Finley. It combines the Old English elements 'tyne', meaning an enclosure or hedge, and 'leah', meaning a meadow or clearing. As a contemporary creation, it follows the popular trend of 'lee' ending names for girls.
