Eorlingas

Eorlingas or Eorlings was a name the Rohirrim sometimes used for themselves, as followers and descendants of their first King, Eorl.

The word was used in a call to arms chanted by King Théoden when Gandalf had healed him:
It was also used by the armed men standing nearby after the healing, by Háma when he suggested Éowyn as the regent of Rohan during the absence of King Théoden, by Théoden and his riders, and by Théoden to rally the Rohirrim during the Battle of the Hornburgand the Battle of the Pelennor Fields.
