In the fiction of J. R. R. Tolkien
, Eä is the Quenya language
name for the universe
. The word comes from the Quenya word for to be
. Thus, Eä is the World that Is
, as distinguished from the World that Is Not
. It may thus be assumed that everything outside Eä, including the Timeless Halls
of Ilúvatar, have no material form.
