A word in the fictional language of Quenya (which was made by J.R.R. Tolkien and is a type of Elvish). It means "Strider" in Quenya and was the name given to all the descendants of Aragorn (son of Arathorn, from the Lord of the Rings). The name was given by Peregrin Took or Pippin who continued to address Aragorn as "Strider" even in front of high ranking officials. Aragorn then said that the name of his house would be "Telcontar", the equivalent of Strider in Quenya.
Eldarion, son of Aragorn, was the first of the House of Telcontar.
