A Ringer is recent coinage for a fan of The Lord of the Rings somewhat in the same line as fanboys, fangirls, otaku, and Trekkies, but markedly different. One of the differences is that, whereas also every Star Trek fan is called a Trekker or Trekkie, not all Lord of the Rings fans agree on the designation of the group. Many people who consider themselves fans of Lord of the Rings do not find the posthumously published works of Tolkien like The Silmarillion or The History of Middle-earth to be interesting. Therefore, in some cases Ringer might apply to someone who is a fan of the Lord of the Rings books or movies, but not of Tolkien's extended work. "Ringers: Lord of the Fans" is the name of a comedic documentary, released in 2005, that covers the influence of The Lord of the Rings and features actors such as Dominic Monaghan and Elijah Wood.
A Tolkienist is someone who studies the work of Tolkien: this usually refers to students of the Elvish languages (see Tolkien research). A Tolkienist can also be described as a hard-core fan of Tolkien's work, one who studies the work with the same amount of interest (or more) that others study non-fictional subjects. Many fans prefer this term, as it isn't limited to The Lord of the Rings. As with the term Ringer, there is no group consensus on this designation.
There are also other, less widely used terms describing Tolkien fans, such as Tolkienite, Tolkienophile, or Tolkiendil (an Anglo-Quenya compound). A very early term never widely adopted was LoTRian.
