In Latin, sylva means "wood" or "forest," and is derived from Sylvanus/Selvans, the name of the Italic/Etruscan god of the woods and fields—a god sometimes identified with the Greek god Pan or the Gaulish gods Sucellos and/or Cernunnos.

“But there, my friends, songs like trees bear fruit only in their own time and their own way: and sometimes they are withered untimely."

-Treebeard, 3019 of the Third age of Middle Earth
