What is "tailtiu"

Tailtiu or Tailltiu (; modern spelling: Tailte) (also known as Talti) is the name of a presumed goddess from Irish mythology. The goddess's name is linked to Teltown (< OI Óenach Tailten) in Co. Meath, site of the Óenach Tailten. A legendary dindsenchas "lore of places" poem relates a myth connecting the presumed goddess Tailtiu with the site. However, linguistic analysis of the name reveals that Tailtiu as a place-name derives from a loan word of Brythonic origin represented by the Welsh telediw "well formed, beautiful." The mythological character of Tailtiu likely derives her name from the place-name.
