He goes by many names: Strider, Isildur’s Heir, Elessar, Elendil’s Son of Numenor. Yet most know him as Aragorn - or as the frequently spoken Aragorn, son of Arathorn. One observant redditor noted that the latter moniker was said at least 16 times in the books. Apparently, author J.R.R. Tolkien really wanted readers to know who Aragorn’s dad was.
